+# R4 UI-conformity sweep — v1.4.27
+
+Read-only walk of every same-class surface in the app on `develop` (HEAD
+`617d4518`). Compares each concrete instance against its siblings and
+flags visual / structural drift: heading weight, card chrome, form
+rhythm, spacing scale, typography scale, button positions, icon sizes,
+Dialog / Sheet chrome, table chrome, empty-state shape, loading
+skeleton shape, colour tokens, dark-mode parity.
+
+Maintainer framing: "no duplicates, everything looks the same,
+everything is conform." Intentional variants (admin dense tables,
+narrative copy in Coach) are noted and skipped from the drift list.
+
+---
+
+## Severity legend
+
+- **P0** — same-class instances diverge enough that the surfaces no
+  longer read as one app; fix before tagging v1.4.27.
+- **P1** — token / weight / spacing drift the user notices when
+  switching between two routes of the same family; queue inside the
+  v1.4.27 polish bucket.
+- **P2** — minor inconsistency that surveys cleanly under a single
+  rule once codified; defer or roll into the next pass.
+- **P3** — informational / convention note, no user-visible action.
+
+---
+
+## Headline drift (top of the sweep)
+
+1. **P0** — Settings vs Admin section chrome diverge on heading
+   element + page-header presence. Settings sections open with
+   `<section aria-labelledby>` + `<h1 className="text-2xl
+   font-semibold tracking-tight">` + a description `<p>`; admin
+   sections open with `<div className="bg-card border-border
+   rounded-xl border p-6">` directly and use `<div className="text-lg
+   font-semibold">` (not an `<h2>`) for the card title. Result:
+   semantic landmark + Marc-Voice page-header on `/settings/*`, no
+   landmark + visual-only title on `/admin/*`. (See §3.)
+2. **P0** — Two tab-strip implementations coexist. Insights tab
+   strip is a custom `<nav>` of `min-h-11 rounded-full` `<Link>` pills
+   with `bg-primary/10 text-primary` active state, sticky `top-0` +
+   right-edge fade; Feedback inbox uses the shadcn `<Tabs>`
+   primitive with `h-9 bg-muted` `TabsList`, `data-[state=active]:bg-background`
+   pill. The two strips do not feel like the same control. (See §10.)
+3. **P0** — Loader spinner palette + size + motion-reduce vocabulary
+   is unconstrained. Eighteen distinct `Loader2 className="…"`
+   signatures across the codebase: `text-primary h-6 w-6`,
+   `text-muted-foreground h-5 w-5`, `text-dracula-purple h-5 w-5`,
+   raw `h-3 w-3`, mixed inclusion of `motion-reduce:animate-none`.
+   Two adjacent surfaces (insights mother page vs insight-status-card
+   loading state) paint different colours for the same "loading"
+   semantic. (See §8.)
+4. **P1** — `<EmptyState>` size + variant choices read inconsistent.
+   Insights sub-pages all pass `icon={<X className="size-6" />}`
+   without an explicit `size` prop. Daily Briefing uses
+   `variant="plain"` + `icon size-5`. Admin feedback inbox uses
+   `size="compact"` + `icon size-5`. Admin recent-audit uses
+   `size="compact" variant="plain" icon size-5`. Inside the seven
+   insights sub-pages every empty-state CTA passes `<Button size="sm"
+   asChild>` — but MB7 / CF-36 added `ctaSize="lg"` to the
+   primitive and no consumer uses it. (See §7.)
+5. **P1** — `bg-card border-border rounded-xl border p-6` is the
+   de-facto "section card" chrome but it is hand-rolled in 21
+   files (settings + admin) instead of being a shared primitive.
+   Drift creeps in (`thresholds-editor-section.tsx` adds
+   `scroll-mt-28`; account-section.tsx has 4 hand-rolled copies;
+   admin sections add it inside the section root rather than
+   wrapping the section). (See §3.)
+

+
+## 1. Dashboard tiles (TrendCard / GLP-1 / Health Score / Briefing)
+
+| Instance | Card chrome | Headline weight | Spacing | Flags |
+|---|---|---|---|---|
+| `<TrendCard>` (charts/trend-card.tsx:213) | `bg-card border-border flex h-full w-full min-w-0 flex-col rounded-xl border p-4 md:p-6` | label `text-xs font-medium`, value `text-3xl font-bold` | `mt-2 gap-x-1.5`, `pt-1` for sub-row | **P0** — only tile in the codebase that uses `font-bold` for its headline number; every other tile uses `font-semibold` (Glp1-Tile drug-line, Health-Score number, sub-page chart sticky values). |
+| `<Glp1Tile>` (dashboard/glp1-tile.tsx:244) | `bg-card/65 relative overflow-hidden rounded-xl border px-4 py-4 shadow-sm backdrop-blur-sm` | title `text-sm font-semibold tracking-tight`, drug-line `text-lg font-semibold tabular-nums` | `pb-3` between rows, `space-y-2 pt-2` for chart pane | **P1** — `bg-card/65` + `backdrop-blur-sm` is unique to Glp1-Tile and Health-Score-Card; every other tile uses solid `bg-card`. Glp1 schedule pills use `border-dracula-green/30 bg-dracula-green/10` directly — only consumer of this exact green-pill recipe. |
+| `<HealthScoreCard>` (insights/health-score-card.tsx:228) | `bg-card/65 rounded-xl border px-4 py-4 shadow-sm backdrop-blur-sm` | label `text-[10px] font-semibold tracking-[0.18em] uppercase`, number `text-5xl font-semibold sm:text-6xl` | `flex flex-col gap-3`, `flex items-baseline gap-1` | **P1** — only instance of `text-[10px]` + `tracking-[0.18em]` in the app. Trend-card labels use `text-xs leading-5 font-medium tracking-wide uppercase`. Both convey "metric label" semantically but the typography vocabulary diverges. |
+| `<DailyBriefing>` (insights/daily-briefing.tsx:260) | `<Card>` primitive (`bg-card text-card-foreground flex flex-col gap-6 rounded-xl border py-6 shadow-sm`) | `CardTitle` `text-base font-semibold` | `CardHeader pb-3`, key-finding `space-y-2`, finding rows `border-border/60 bg-card/40 rounded-md p-3` | **P2** — only dashboard surface that uses the `<Card>` primitive; the other three tiles hand-roll their wrapper. Findings-title pad: `text-[11px] font-semibold tracking-wide uppercase` — yet another distinct meta-label typography stack (cf. health-score-card `[10px]` and trend-card `xs`). |
+
+### Drift summary (dashboard tiles)
+
+- **P0** — headline weight inconsistency: TrendCard uses `font-bold`
+  on the latest reading; every other tile in the strip uses
+  `font-semibold` for the same role. Fix: align TrendCard headline
+  to `font-semibold` (or migrate every tile to `font-bold`; pick one).
+- **P1** — three "meta-label uppercase tracking" recipes live side
+  by side: trend-card `text-xs tracking-wide`, health-score-card
+  `text-[10px] tracking-[0.18em]`, daily-briefing key-findings-title
+  `text-[11px] tracking-wide`. Codify a single
+  `text-[11px] tracking-wide font-semibold uppercase` and migrate.
+- **P1** — `bg-card/65 + backdrop-blur-sm` is used only by Glp1-Tile
+  and HealthScoreCard. Either roll it into a shared
+  `dashboard-tile.tsx` wrapper or drop the `/65 + blur` so every
+  tile sits on solid `bg-card`.
+- **P2** — Daily Briefing is the only dashboard surface that goes
+  through the `<Card>` primitive (12 px header / 24 px body
+  internal padding via `gap-6 py-6`). The other tiles use `px-4 py-4`
+  hand-rolled chrome. Consider migrating every dashboard tile to a
+  single primitive.

+
+## 2. Insights sub-pages — 7 routed sub-pages + report
+
+| Sub-page | Shell | Empty-state | Status card | Spacing flag |
+|---|---|---|---|---|
+| `/insights/blutdruck` | `<SubPageShell>` + description | `<EmptyState icon size-6>` + `<Button size="sm" asChild>` | `<InsightStatusCard>` | uses `BLOOD_PRESSURE_SYS` gate; CTA → `/measurements?add=BLOOD_PRESSURE` |
+| `/insights/bmi` | `<SubPageShell>` + description | TWO branches: `BMI` empty + `heightCm` empty | `<InsightStatusCard>` | dual empty branches feel inconsistent (one points to `/measurements`, other to `/settings/account`) |
+| `/insights/gewicht` | `<SubPageShell>` + description | `<EmptyState icon size-6>` | `<InsightStatusCard>` | matches blutdruck. |
+| `/insights/medikamente` | `<SubPageShell>` + description | `<EmptyState icon size-6>` → `/medications` | `<InsightStatusCard>` + per-med `<Card>` grid | uses `<Loader2 text-primary h-6 w-6>` for primary loader (matches mother page); inner per-med loader is `text-primary h-4 w-4` |
+| `/insights/puls` | `<SubPageShell>` + description | `<EmptyState icon size-6>` | `<InsightStatusCard>` + `<Vo2MaxChartRow>` | conforming |
+| `/insights/schlaf` | `<SubPageShell>` + description | `<EmptyState icon size-6>` | NO `<InsightStatusCard>` — Sleep sub-page is the only one without the per-section assessment slot | **P1** — six sub-pages mount `<InsightStatusCard>` underneath the chart; Sleep does not. Either Sleep should pick up the assessment (matching the pattern) or the assessment slot should be documented as optional. |
+| `/insights/stimmung` | `<SubPageShell>` + description | `<EmptyState icon size-6>` → `/mood` | `<InsightStatusCard>` | conforming |
+
+### Drift summary (insights sub-pages)
+
+- **P1** — Sleep is the only sub-page that omits the `<InsightStatusCard>`
+  "assessment" slot. Either add the assessment for sleep (status text
+  + cached badge + last-updated footer) or reframe the slot as
+  optional in the SubPageShell contract.
+- **P2** — BMI's two-branch empty-state is unique: every other
+  sub-page has exactly one empty-state path. The BMI dual branch is
+  legitimate (zero WEIGHT vs zero `heightCm`) but the second branch
+  (`heightCm`) uses a different translation namespace
+  (`insights.bmiEmpty*`) from the gated empty-state
+  (`insights.emptyState.bmi.*`). Pick a single namespace.
+- **P2** — Every empty-state in the seven sub-pages passes `<Button
+  size="sm" asChild>` for the CTA. The `EmptyState` primitive added
+  `ctaSize="lg"` (MB7 / CF-36) so the inner button lifts to
+  `min-h-11 w-full sm:w-auto`. Zero current consumers — adopt or
+  remove the prop.
+- **P3** — `useQuery({ queryKey: ["analytics"] })` is hand-rolled
+  inline in five sub-pages (blutdruck, bmi, gewicht, puls, schlaf)
+  with identical `queryFn` + `staleTime` + `enabled` flags. The
+  `<InsightsLayoutShell>` already mounts the same query (F19);
+  consumers ride the dedup but the hand-rolled copy is dead code in
+  spirit. Extract a `useAnalyticsQuery()` hook.
+
+---
+
+## 3. Settings vs admin sections cross-area
+
+| Surface | Root | Heading | Card chrome | Section title element |
+|---|---|---|---|---|
+| `settings/account-section.tsx` | `<section aria-labelledby … className="space-y-6">` | `<h1 text-2xl font-semibold tracking-tight>` + `<p text-muted-foreground text-sm>` | 4× hand-rolled `<div className="bg-card border-border rounded-xl border p-6">` | `<h2 text-lg font-semibold>` |
+| `settings/api-section.tsx` | `<section aria-labelledby … className="space-y-6">` | matches account-section header | hand-rolled `bg-card border-border rounded-xl border p-6` | `<h2 text-lg font-semibold>` |
+| `settings/integrations-section.tsx` | `<section aria-labelledby … className="space-y-6">` | matches | matches | `<h2 text-lg font-semibold>` |
+| `settings/notifications-section.tsx` | `<section aria-labelledby … className="space-y-6">` | matches | matches | `<h2 text-lg font-semibold>` |
+| every other `settings/*-section.tsx` | identical | identical | identical | identical |
+| `admin/general-settings-section.tsx` | `<div className="bg-card border-border rounded-xl border p-6">` — **no `<section>`, no aria-labelledby**, no page-level h1 | NONE — title is the card title | inline | `<div className="text-lg font-semibold">` (NOT a heading element) |
+| `admin/system-status-section.tsx` | `<div className="space-y-6">` then `<div className="bg-card …">` | NONE | inline | `<div className="text-lg font-semibold">` |
+| `admin/api-token-overview-section.tsx` | direct card | NONE | inline | `<div className="text-lg font-semibold">` |
+| `admin/recent-audit-preview.tsx` | `<section aria-labelledby …>` ✓ | ✓ but uses `<h2 className="text-lg font-semibold">` (not h1) | inline | matches the section heading itself |
+| `admin/system-status-summary.tsx` | `<section aria-labelledby …>` ✓ | `<h2 text-lg font-semibold>` | inline | matches |
+| `admin/host-metrics-chart.tsx` | `<section aria-labelledby …>` ✓ | `<h2 id text-sm font-semibold>` | inline | matches |
+| `admin/bug-report-section.tsx` | `<div>` | `<h2 text-lg font-semibold>` | inline | h2 |
+| `admin/glitchtip-section.tsx` | `<div>` | `<h2 text-lg font-semibold>` | inline | h2 |
+| `admin/umami-section.tsx` | `<div>` | `<h2 text-lg font-semibold>` | inline | h2 |
+| `admin/app-log-preview-section.tsx` | `<div>` | `<h2 text-lg font-semibold>` | inline | h2 |
+| `admin/web-push-vapid-section.tsx` | `<div>` | `<h2 text-lg font-semibold>` | inline | h2 |
+| `admin/general/services/system-status/api-token/login-overview/user-management/coach-feedback/ai-quality/reminders` | `<div>` | `<div className="text-lg font-semibold">` ← **NOT a heading** | inline | div |
+
+### Drift summary (settings vs admin)
+
+- **P0** — Two parallel "section" recipes coexist. Settings has a
+  full landmark + page-header + body-card stack. Admin sections
+  often skip the landmark + page header entirely and start at the
+  card body. Either:
+  - bring admin sections into line with settings (`<section
+    aria-labelledby>` + page `<h1>` + body card), or
+  - codify a shared `<AdminSection>` primitive that owns the
+    landmark + heading + card chrome and migrate every admin
+    section onto it.
+- **P0** — Inside admin sections, 11 surfaces use `<div className="text-lg
+  font-semibold">` for the card title (no heading element). This is
+  both a semantic drift (no `<h2>`) and a visual drift against the
+  6 admin sections that DO use `<h2 className="text-lg font-semibold">`.
+  Pick one and migrate.
+- **P1** — `bg-card border-border rounded-xl border p-6` is repeated
+  21 times. Extract a `<SectionCard>` primitive so the chrome stays
+  single-source-of-truth (and so a future radius / shadow tweak
+  doesn't require 21 edits).
+- **P2** — Settings page header is `text-2xl font-semibold tracking-tight`;
+  admin recent-audit-preview / system-status-summary use `text-lg
+  font-semibold` for their landmark heading. Different visual
+  weight for what is semantically the same role on each route. Pick
+  one and migrate.
+

+
+## 4. Dialogs / Sheets / ResponsiveSheet
+
+| Surface | Primitive | Header chrome | Max width / height | Close affordance |
+|---|---|---|---|---|
+| `dialog.tsx` (primitive) | Radix Dialog | `<DialogHeader pr-9>` | `max-w-[calc(100%-2rem)] max-h-[calc(100dvh-2rem)] sm:max-w-lg` | absolute top-right `min-h-9 min-w-9` (MB2 — explicit 36px floor per Decision I) |
+| `sheet.tsx` (primitive) | Radix Dialog (side) | `<SheetHeader p-4>` | `w-3/4 sm:max-w-sm` | absolute `top-4 right-4`, `opacity-70`, `rounded-xs` — **smaller, no `min-h-9` floor, no aria-label** |
+| `responsive-sheet.tsx` | Sheet or Dialog | `<SheetHeader p-4 pr-12>` mobile, plain `<DialogHeader>` desktop | mobile: `max-h-[90dvh] rounded-t-2xl`; desktop: `sm:max-w-md` | inherits from underlying primitive |
+| `coach-drawer.tsx` (`<Sheet>` direct) | Radix Sheet (custom) | hand-rolled `<SheetHeader flex-row items-center gap-2 border-b p-3 sm:gap-3 sm:p-4>` | mobile: `h-[95dvh] rounded-t-2xl`; desktop: `sm:max-w-[720px] lg:!max-w-[min(960px,75vw)] xl:!max-w-[1080px]` | `showCloseButton={false}` — header carries own `<SheetClose>` |
+| `phase-config-dialog.tsx` | `<Dialog>` direct | DialogHeader | `sm:max-w-md` | primitive |
+| `feedback-inbox-section.tsx` dialog | `<Dialog>` direct | DialogHeader | `max-h-[85vh] overflow-y-auto sm:max-w-2xl` | primitive |
+| `doctor-report-dialog.tsx` | `<Dialog>` direct | DialogHeader | (see file) | primitive |
+| `medications/intake-history-list.tsx` (2 sheets) | `<ResponsiveSheet>` | shared | inherits | inherits |
+| `medications/inventory-section.tsx` | `<ResponsiveSheet>` | shared | inherits | inherits |
+| `medications/SideEffectsSection.tsx` | `<ResponsiveSheet>` | shared | inherits | inherits |
+| `mood/mood-list.tsx` edit | `<Dialog>` direct (NOT ResponsiveSheet) | DialogHeader | primitive default | primitive |
+| `measurements/measurement-list.tsx` edit | `<Dialog>` direct (NOT ResponsiveSheet) | DialogHeader | primitive default | primitive |
+| `targets/target-edit-sheet.tsx` | `<Dialog>` direct (file name implies Sheet, content is Dialog) | DialogHeader | primitive default | primitive |
+| `medications/ResearchModeAcknowledgmentDialog.tsx` | `<Dialog>` direct | DialogHeader | primitive default | primitive |
+
+### Drift summary (Dialogs / Sheets)
+
+- **P0** — Sheet primitive's close-X is visibly smaller than the
+  Dialog primitive's close-X. Sheet: `opacity-70 rounded-xs`
+  (~16px hit target, no min-size, no aria-label). Dialog: `min-h-9
+  min-w-9` with explicit hover/focus chrome and an aria-label. Same
+  affordance, different size + accessibility floor. Bring sheet
+  close-X up to dialog parity.
+- **P0** — Edit dialogs on `measurements`, `mood`, `targets`,
+  `phase-config`, `research-mode-acknowledgment`, and `feedback-inbox`
+  all mount raw `<Dialog>` instead of `<ResponsiveSheet>`. On mobile
+  these surfaces lose the bottom-sheet branch the medication editor,
+  intake history, and side-effects flow already have. Either:
+  - migrate every form-bearing dialog onto `<ResponsiveSheet>`, or
+  - document an explicit "Dialog stays a Dialog when X" rule.
+- **P1** — Coach drawer hand-rolls its `<Sheet>` chrome instead of
+  riding `<ResponsiveSheet>`. The mobile / desktop branch logic, the
+  close affordance, and the header layout duplicate
+  `responsive-sheet.tsx` with slight differences (Coach uses
+  `h-[95dvh]`, ResponsiveSheet uses `max-h-[90dvh]`). Consolidate.
+- **P2** — `targets/target-edit-sheet.tsx` filename says "sheet" but
+  the implementation imports `<Dialog>`. Either rename the file or
+  swap the underlying primitive.
+
+---
+
+## 5. Forms — measurement / mood / medication / settings
+
+| Form | Outer | Field group spacing | Label gap | Notes |
+|---|---|---|---|---|
+| `measurements/measurement-form.tsx:254` | `<form className="space-y-4">` | `<div className="space-y-2">` per label-input | `space-y-2` | Matches the documented convention. |
+| `mood/mood-form.tsx:121` | `<form className="space-y-4">` | `<div className="space-y-2">` | `space-y-2` | Matches. |
+| `mood/mood-list.tsx:527` (edit form) | `<form className="space-y-4">` | `<div className="space-y-2">` | `space-y-2` | Matches. |
+| `medications/medication-form.tsx:526` | `<form className="space-y-4">` | `<div className="space-y-2">` | `space-y-2` | Matches. |
+| `settings/account-section.tsx:350` profile form | `<form className="space-y-4">` | `<div className="space-y-2">` | `space-y-2` | Matches. |
+| `settings/account-section.tsx:613` password form | `<form className="space-y-3">` | `<div className="space-y-2">` | `space-y-2` | **P1** — only form in the codebase using `space-y-3` for the outer rhythm; every other form uses `space-y-4`. |
+| `settings/ntfy-card.tsx:142` | `<form className="space-y-4">` | `<div className="space-y-2">` | `space-y-2` | Matches. |
+| `settings/api-section.tsx:248` (token creation) | `<form className="flex gap-2">` (inline) | — | — | Intentional — single-input + button. Skip. |
+
+### Drift summary (forms)
+
+- **P1** — `settings/account-section.tsx` password-change form uses
+  `space-y-3` for the outer form rhythm. Every other form in the
+  codebase uses `space-y-4`. Align to `space-y-4`.
+- **P3** — Otherwise the `space-y-4` outer / `space-y-2` label-input
+  convention is honoured across 9 forms. Solid.
+
+---
+
+## 6. Tables — settings + admin + new `/settings/api` mobile card-list
+
+| Table | Primitive | Mobile behaviour | Row striping | Notes |
+|---|---|---|---|---|
+| `measurements/measurement-list.tsx:395` | shadcn `<Table>` primitive | `md:hidden` card list in `space-y-2` | `<TableRow>` (hover) | Matches the documented "dual-render" pattern. |
+| `mood/mood-list.tsx` | shadcn `<Table>` primitive | `md:hidden` card list | `<TableRow>` (hover) | Matches. |
+| `medications/intake-history-list.tsx` | shadcn `<Table>` primitive | `md:hidden` card list | `<TableRow>` (hover) | Matches. |
+| `admin/feedback-inbox-section.tsx:132` | raw `<table>` | NO mobile fallback (single `overflow-x-auto` wrap) | `i % 2 === 0 ? "bg-muted/30" : ""` (zebra) | **P1** — only admin table without a mobile card list; the user gets a horizontal scroll. Marc's "no horizontal scroll on mobile" rule. |
+| `admin/api-token-overview-section.tsx:191` | raw `<table table-fixed>` + `<colgroup>` | `md:hidden` card list (`bg-muted/30 border rounded-lg p-3`) | `i % 2 === 0 ? "bg-muted/30" : ""` zebra | Matches the MB5 pattern. |
+| `admin/user-management-section.tsx` | raw `<table>` | `md:hidden` card list | zebra | Matches. |
+| `admin/login-overview-section.tsx` | raw `<table>` | (see file) | zebra | (admin "dense" — intentional variant per dispatch brief; skip from drift) |
+| `admin/coach-feedback-section.tsx` | raw `<table>` | (see file) | zebra | admin dense — skip |
+| `admin/backups-section.tsx` | raw `<table>` | (see file) | zebra | admin dense — skip |
+| `admin/app-log-preview-section.tsx` | raw `<table>` | (see file) | zebra | admin dense — skip |
+| `admin/ai-quality-section.tsx` | raw `<table>` | (see file) | zebra | admin dense — skip |
+| `settings/account-section.tsx` passkey list | raw `<table>` + `md:hidden` div list | dual-render | none | Matches the convention. |
+| `settings/api-section.tsx:90` (endpoints) | raw `<table>` | `<ul className="md:hidden space-y-2">` | none | Matches MB5 mobile card-list. |
+| `settings/api-section.tsx:290` (tokens) | raw `<table>` | `<ul className="md:hidden space-y-2">` | `index % 2 === 0 ? "bg-muted/20" : ""` zebra | Different zebra opacity (`bg-muted/20`) than admin (`bg-muted/30`). Minor. |
+
+### Drift summary (tables)
+
+- **P1** — `admin/feedback-inbox-section.tsx` is the only admin
+  table that lacks a `md:hidden` mobile card-list fallback. On
+  Pixel 5 the user gets horizontal scroll. Add a mobile branch
+  matching the user-management / api-token pattern.
+- **P1** — Settings `api-section` uses `bg-muted/20` zebra striping;
+  every admin table uses `bg-muted/30`. Pick one and apply
+  consistently.
+- **P1** — Two table primitives coexist:
+  - shadcn `<Table>` primitive (measurements / mood / intake-history)
+  - raw `<table className="w-full text-sm">` (every admin + settings
+    table) with hand-rolled headers (`<tr className="text-muted-foreground
+    border-b text-xs">`).
+  Either:
+  - retrofit the raw tables onto the `<Table>` primitive, or
+  - document the raw `<table>` recipe as the "dense" variant
+    (admin / settings) and add a primitive for it.
+- **P2** — Mobile card-list outer class drift:
+  - admin api-tokens uses `bg-muted/30 border-border overflow-hidden rounded-lg border p-3`
+  - settings api-tokens uses `bg-muted/30 border-border space-y-2 rounded-lg border p-3`
+  - settings api-endpoints uses `bg-muted/30 border-border space-y-1.5 rounded-lg border p-3 text-xs`
+  - measurement-list uses (see file)
+  Pick one and codify a `<MobileListCard>` primitive.

+
+### Drift summary (empty states)
+
+- **P1** — `ctaSize="lg"` (MB7 / CF-36) is on the primitive but
+  ZERO consumers pass it. Decide: adopt for every CTA-bearing
+  empty-state (the seven insights sub-pages would benefit at
+  mobile widths) or remove from the primitive.
+- **P2** — `size="compact"` + `variant="plain"` is used by two
+  admin previews (feedback-inbox tab body, recent-audit) and
+  Daily Briefing. Three different combinations across three
+  surfaces: default+default+icon-6 (most), compact+default+icon-5
+  (feedback inbox), compact+plain+icon-5 (recent-audit), default+plain+icon-5
+  (daily-briefing). The icon-5 + plain combination wants a single
+  recipe ("inline preview empty"). Codify.
+- **P3** — `correlation-card.tsx` empty-state never has a CTA; the
+  consumer pages can act on the empty-row. Consider whether a
+  passive empty (no action prop) is the same primitive or a
+  separate inline message.

+## 8. Loading skeletons + spinners
+
+### Skeleton shapes
+
+| Surface | Shape |
+|---|---|
+| `ui/skeleton.tsx` (primitive) | `bg-muted/60 animate-pulse rounded-md motion-reduce:animate-none` |
+| `insights/daily-briefing.tsx` BriefingSkeleton | hand-rolled: `bg-muted/60 h-3 w-{ratio}/12 animate-pulse rounded` + `border-border/40 bg-card/30 h-16 rounded-md border` rows (does NOT use the `<Skeleton>` primitive). |
+| `dashboard/glp1-tile.tsx` skeleton | hand-rolled `bg-muted/40 mb-3 h-4 w-24 animate-pulse rounded` + `bg-muted/40 h-32 w-full animate-pulse rounded` (uses `/40` opacity, NOT the primitive's `/60`). |
+| `chart-skeleton.tsx` and friends | various |
+
+### Spinner colour + size (Loader2)
+
+Eighteen distinct class signatures observed; the meaningful
+clusters:
+
+| Cluster | Surfaces | Signature |
+|---|---|---|
+| **Primary loading (large)** | insights mother page, insights/medikamente, weekly-report-view | `text-primary h-6 w-6 animate-spin motion-reduce:animate-none` |
+| Primary loading (large, no motion-reduce) | account-section | `text-primary h-8 w-8 animate-spin` |
+| **Insight status card** | insight-status-card | `text-dracula-purple h-5 w-5 animate-spin motion-reduce:animate-none` |
+| **Inline button** | settings/advanced-section, settings/about-section, settings/account-section, … | `mr-2 h-4 w-4 animate-spin motion-reduce:animate-none` (or `mr-1 h-3.5 w-3.5`) |
+| **Inline + muted** | admin/api-token-overview-section, admin/feedback-inbox-section | `text-muted-foreground h-4 w-4 animate-spin motion-reduce:animate-none` |
+| **Inline (tiny, no colour)** | insight-advisor-card (7 instances) | `h-3.5 w-3.5 animate-spin` (no `motion-reduce`) |
+| **Per-medication compliance row** | insights/medikamente inner | `text-primary h-4 w-4 animate-spin motion-reduce:animate-none` |
+
+### Drift summary (skeletons + spinners)
+
+- **P0** — Spinner colour drift inside the same conceptual surface.
+  On `/insights`, the mother page paints `text-primary h-6 w-6`,
+  but `<InsightStatusCard>` (which loads on the same page below the
+  mother) paints `text-dracula-purple h-5 w-5`. Same loading
+  semantic, two colours, two sizes. Codify a `<Spinner>` primitive
+  with `size: "sm" | "md" | "lg"` and `tone: "primary" | "muted" |
+  "accent"`, and migrate.
+- **P0** — `motion-reduce:animate-none` inclusion is inconsistent.
+  Of the 18 signatures, 9 include the override and 9 don't. The
+  insight-advisor-card has SEVEN Loader2 instances and NOT ONE
+  carries `motion-reduce:animate-none`. With the docs convention
+  pointing at "honour `prefers-reduced-motion`", this is an a11y
+  drift. Bake `motion-reduce:animate-none` into a `<Spinner>`
+  primitive.
+- **P1** — Two skeleton patterns coexist: the `<Skeleton>` primitive
+  with `bg-muted/60` + auto `motion-reduce` vs hand-rolled
+  `bg-muted/{40,60} animate-pulse` divs. Daily-Briefing's
+  `<BriefingSkeleton>` and Glp1-Tile's skeleton never use the
+  primitive. Migrate or document the hand-rolled exception.
+
+---
+
+## 9. Buttons + icon buttons (post-MB2 lift)
+
+The Button primitive (`ui/button.tsx`) already encodes the size
+contract: `default h-10`, `xs h-6`, `sm h-8`, `lg h-11`, `icon size-10`,
+`icon-xs size-6`, `icon-sm size-8`, `icon-lg size-11`.
+
+| Surface | Variant + size | Drift |
+|---|---|---|
+| Dashboard tiles — no inline buttons | — | n/a |
+| GLP-1 tile tab strip / range strip | hand-rolled `<button>` with `min-h-11` + `rounded` | **P1** — does not use the `<Button>` primitive; bespoke pill styling. The Button primitive's `xs` (`h-6`) and `sm` (`h-8`) sizes don't fit but a new `pill` variant could. |
+| Insights tab strip pills | hand-rolled `<Link className="inline-flex min-h-11 rounded-full border">` | **P0** — see §10. Bespoke. |
+| Insights tab strip regenerate | hand-rolled `<button className="h-11 w-11 rounded-full">` (cf. Button `size="icon-lg"` which is `size-11`) | **P1** — could use `<Button size="icon-lg" variant="ghost">`. Hand-rolled hover state. |
+| Daily Briefing regenerate CTA | `<Button type="button" size="sm" variant="outline">` | conform |
+| Sub-page empty-state CTA | `<Button size="sm" asChild>` | conform (every one of the 7 sub-pages) |
+| API token creation | `<Button type="submit" variant="outline" size="sm">` | conform |
+| API token mobile revoke | `<Button variant="outline" size="sm" className="text-destructive border-destructive/30 min-h-11 w-full">` | **P2** — `min-h-11` overrides `size="sm"`'s `h-8`. Either use `size="lg"` (already `h-11`) or move the `min-h-11` to a documented "mobile revoke" variant. |
+| API token desktop revoke | `<Button variant="ghost" size="icon" className="text-destructive h-8 w-8">` | **P2** — overrides `size="icon"` (`size-10`) with `h-8 w-8`. Either use `size="icon-sm"` (already `size-8`) or document the override. |
+| Coach launch / drawer buttons | `<Button variant="ghost" size="icon">` etc. | conform |
+
+### Drift summary (buttons)
+
+- **P0** — Insights tab strip pills + regenerate button are
+  hand-rolled outside the `<Button>` primitive. See §10.
+- **P1** — Glp1-Tile pill-style tab + range strip mounts hand-rolled
+  `<button>`s, not the `<Button>` primitive. Decide whether to add
+  a `pill` variant or leave bespoke + document.
+- **P2** — Several inline overrides of the size system: `size="icon"`
+  + `h-8 w-8`, `size="sm"` + `min-h-11`. If the primitive's
+  `icon-sm` (size-8) and `lg` (h-11) sizes do the job, use them.
+  Otherwise expose a clean variant.
+
+---
+
+## 10. Tab strips (insights vs feedback-inbox)
+
+| Strip | Mount | Visual | Active state | Right-edge fade | Tap target |
+|---|---|---|---|---|---|
+| `insights/insights-tab-strip.tsx` | hand-rolled `<nav>` with `<Link>` pills | `min-h-11 rounded-full border px-3 py-1 text-xs font-medium` | `border-primary bg-primary/10 text-primary` | yes (sm:hidden gradient) | `min-h-11` (WCAG 2.5.5 floor) |
+| `ui/tabs.tsx` + `admin/feedback-inbox-section.tsx` | shadcn `<Tabs>` + `<TabsList>` (`bg-muted h-9 p-1`) + `<TabsTrigger>` | TabsTrigger: rectangular `rounded-md border border-transparent px-2 py-1 text-sm`, no `min-h-11` | `data-[state=active]:bg-background text-foreground` (light pill on muted track) | no | `h-9` strip — under 44 px |
+| `ui/tabs.tsx` + `coach-panel/*` | shadcn `<Tabs>` (line variant) | line variant with `after:` underline | underline | n/a | n/a |
+
+### Drift summary (tab strips)
+
+- **P0** — Two completely different visual languages for "tab strip"
+  exist. Insights tab strip = rounded-full pills with a 44 px tap
+  target, sticky, right-edge fade. Feedback inbox + Coach use the
+  shadcn `<Tabs>` primitive: muted-background pill track, 36 px
+  tap target, no fade. The user reads "tab strip" on `/insights`
+  and recognises one control; on `/admin/feedback` they see a
+  different control. Pick a single convention and migrate.
+- **P1** — Feedback inbox's `<TabsList>` is `h-9` and under the
+  44 px WCAG 2.5.5 mobile target floor that the insights strip
+  honours. Fix or document the exception.
+
+---
+
+## 11. Tooltips / Popovers
+
+| Surface | Primitive | Notes |
+|---|---|---|
+| `ui/tooltip.tsx` | Radix Tooltip via shadcn | base recipe: `bg-popover text-popover-foreground border-border px-3 py-1.5 text-xs text-balance shadow-md` |
+| `ui/popover.tsx` | Radix Popover (added MB3) | base: `bg-popover text-popover-foreground border-border max-w-xs rounded-md border p-3 text-xs shadow-md` |
+| `charts/trend-card.tsx` | `<TooltipContent className="bg-muted border-border text-foreground">` | **P1** — overrides `bg-popover` with `bg-muted` and `text-popover-foreground` with `text-foreground`. Distinct visual treatment from every other tooltip. |
+| `insights/personal-record-badge.tsx` | `<TooltipContent>` | uses primitive default — conform |
+| `targets/target-card.tsx` (2× tooltips) | `<TooltipContent>` | uses primitive default — conform |
+| `targets/range-bar.tsx` | `<TooltipContent>` | uses primitive default — conform |
+| `layout/sidebar-nav.tsx` (5× tooltips) | `<TooltipContent side="right" sideOffset={8}>` | uses primitive default — conform |
+| `admin/api-token-overview-section.tsx` | `<TooltipContent>{value}</TooltipContent>` | uses primitive default — conform |
+| `insights/coach-panel/coach-input.tsx` | `<Popover>` (MB3 swap) | uses primitive default — conform |
+
+### Drift summary (tooltips / popovers)
+
+- **P1** — `trend-card.tsx` is the only consumer that overrides
+  the tooltip surface tokens to `bg-muted text-foreground`. Either:
+  - codify a `variant="filled"` on the primitive and migrate, or
+  - drop the override so trend-card uses the same `bg-popover`
+    surface as every other tooltip.
+- **P3** — Otherwise tooltips + popovers ride the primitive cleanly.
+
+---
+
+## 12. Charts (width-fluidity, Y-axis ticks, x-axis tick formatting)
+
+| Chart | XAxis tick fontSize / fill | YAxis tick width / mode | Container | Notes |
+|---|---|---|---|---|
+| `charts/health-chart.tsx` (canonical) | `{ fontSize: 11, fill: "var(--muted-foreground)" }`, `tickLine={false}`, `axisLine={false}`, `padding={{ left: 10, right: 10 }}`, `tickMargin={10}` | `tick fontSize 11 + muted-foreground`, `width={yAxisWidth}` (dynamic), `tickMargin={10}`, unit appended via `unit` prop | `<ResponsiveContainer width="100%" height="100%">`, margin `{ top: 10, right: 8, bottom: 8, left: 8 }` | reference shape |
+| `charts/mood-chart.tsx` | identical XAxis recipe | YAxis: `domain={[1,5]} ticks={[1,2,3,4,5]} width={65} tickMargin={6}` — **`tickMargin=6` instead of `10`**, fixed `width=65` instead of dynamic | identical container | **P1** — mood chart tickMargin diverges (`6` vs `10`) so labels sit closer to axis than every other chart. |
+| `charts/medication-compliance-chart.tsx` / `compliance-heatmap.tsx` | (see file) — heat-map style, intentional variant | n/a | (see file) | skip — different visualisation |
+| `charts/sparkline-chart.tsx` | (see file) | (see file) | (see file) | skip — sparkline, intentional |
+| `medications/DrugLevelChart.tsx` | (see file) | (see file) | (see file) | skip — domain-specific |
+
+### Drift summary (charts)
+
+- **P1** — Mood chart's YAxis uses `tickMargin={6}` while every
+  other line chart uses `tickMargin={10}`. Tiny visual drift the
+  eye catches when flipping between `/insights/blutdruck` (10) and
+  `/insights/stimmung` (6). Align to 10.
+- **P3** — Both charts share their tick fontSize (`11`), fill
+  (`var(--muted-foreground)`), `tickLine={false}`, `axisLine={false}`
+  recipes — solid. Use of `var(--muted-foreground)` over raw hex
+  in axis chrome is correct (no token leak).
+
+---
+
+## Outliers summary (single grep, one place)
+
+| Surface | Outlier | Severity |
+|---|---|---|
+| `charts/trend-card.tsx:243` | `font-bold` headline value (every other tile uses `font-semibold`) | P0 |
+| `insights/insights-tab-strip.tsx` | custom rounded-full pills + sticky + fade — completely different shape from `<Tabs>` primitive | P0 |
+| `admin/*-section.tsx` (11×) | `<div className="text-lg font-semibold">` card title (not a heading element); every other admin/settings section uses `<h2>` | P0 |
+| `admin/general-settings-section.tsx` (and 10 siblings) | no `<section aria-labelledby>` landmark, no page `<h1>`; settings has both | P0 |
+| `insights/insight-status-card.tsx:40` | `text-dracula-purple h-5 w-5` Loader2 (every other "primary loading" loader uses `text-primary h-6 w-6`) | P0 |
+| `ui/sheet.tsx:78` | close-X smaller + no aria-label (Dialog close-X is `min-h-9 min-w-9` with label) | P0 |
+| `mood/mood-list.tsx`, `measurements/measurement-list.tsx`, `targets/target-edit-sheet.tsx`, `feedback-inbox-section.tsx` dialog | raw `<Dialog>` mounts where `<ResponsiveSheet>` would give the mobile bottom-sheet branch | P0 |
+| `admin/feedback-inbox-section.tsx` | only admin table without `md:hidden` mobile card-list fallback | P1 |
+| `insights/schlaf/page.tsx` | only insights sub-page without `<InsightStatusCard>` | P1 |
+| `settings/account-section.tsx:613` | only form using `space-y-3` outer rhythm (others use `space-y-4`) | P1 |
+| `dashboard/glp1-tile.tsx`, `insights/health-score-card.tsx` | only `bg-card/65 backdrop-blur-sm` consumers; other tiles use solid `bg-card` | P1 |
+| `charts/mood-chart.tsx` YAxis | `tickMargin={6}` (others `=10`) | P1 |
+| `charts/trend-card.tsx:321` TooltipContent | `bg-muted text-foreground` override; every other tooltip uses primitive default | P1 |
+| `settings/api-section.tsx` token table | zebra `bg-muted/20`; admin tables use `bg-muted/30` | P1 |
+| `insights-tab-strip` regenerate button | hand-rolled `h-11 w-11 rounded-full`; Button `size="icon-lg"` would match | P1 |
+| `Glp1Tile` tab strip + range strip | hand-rolled `<button>`s outside the `<Button>` primitive | P1 |
+| Empty-state primitive `ctaSize="lg"` | added MB7/CF-36; zero consumers | P1 |
+| Dashboard "meta-label uppercase tracking" recipes | three variants (`text-xs tracking-wide`, `text-[10px] tracking-[0.18em]`, `text-[11px] tracking-wide`) | P1 |
+| `bg-card border-border rounded-xl border p-6` | repeated 21 times instead of a shared `<SectionCard>` | P1 |
+| Daily-Briefing + Glp1-Tile skeletons | hand-rolled `bg-muted/{40,60} animate-pulse` divs instead of `<Skeleton>` primitive | P1 |
+| Loader2 `motion-reduce:animate-none` inclusion | 9 of 18 signatures include it; insight-advisor-card has 7 instances and 0 include it | P1 |
+| `insights/bmi/page.tsx` empty-state | two separate empty branches with different translation namespaces | P2 |
+| `targets/target-edit-sheet.tsx` | filename ends in `-sheet` but imports `<Dialog>` | P2 |
+| Mobile card-list outer class | three subtly different recipes across api-tokens / api-endpoints / measurements | P2 |
+| Settings api-tokens revoke buttons | size overrides (`size="icon"` + `h-8 w-8`, `size="sm"` + `min-h-11`) | P2 |
+
+---
+
+## Intentional variants noted and skipped
+
+- Admin "dense" tables (`login-overview`, `coach-feedback`,
+  `backups`, `app-log-preview`, `ai-quality`) — raw `<table>` + zebra
+  striping + tighter padding. Per the dispatch brief this is the
+  documented admin density variant; skipped from the drift list.
+- `<ChartEmptyState>` is a separate primitive from `<EmptyState>`
+  by design (charts have different aspect-ratio + layout
+  constraints).
+- `<HeroStrip>` greeting is `text-2xl sm:text-[28px] font-semibold
+  tracking-tight` — this is a page hero, not a card heading, so its
+  scale legitimately diverges from card titles.
+- Coach drawer's narrative copy density and the assistant
+  message-bubble layout are domain-specific (Coach is a
+  conversation surface, not a data surface); not compared against
+  insights cards.
+
+---
+
+## Recommended top-down fixes (effort-ordered, for v1.4.27 polish)
+
+1. **Settings/admin landmark + heading parity.** Pick one recipe
+   (`<section aria-labelledby>` + page `<h1>` + body
+   `<SectionCard>` with `<h2>` title) and migrate the 11 admin
+   sections that use `<div>` shell + `<div>` title.
+2. **Loader2 → `<Spinner>` primitive.** New file
+   `src/components/ui/spinner.tsx` with `size + tone` props and
+   built-in `motion-reduce:animate-none`. Replace the 18+
+   signatures with `<Spinner size="lg" tone="primary" />` etc.
+3. **`<SectionCard>` + `<DashboardTile>` primitives.** Roll the
+   21 hand-rolled `bg-card border-border rounded-xl border p-6`
+   wrappers into one primitive; roll the dashboard tile chrome
+   (`bg-card/65 backdrop-blur-sm` vs solid; `px-4 py-4` vs Card's
+   `gap-6 py-6`) into a second primitive. Decide once whether
+   tiles use blur.
+4. **TrendCard headline weight.** Drop `font-bold` → `font-semibold`
+   to match every other tile.
+5. **Tab strip consolidation.** Either:
+   - migrate feedback-inbox + Coach onto the insights
+     rounded-full sticky pill strip, or
+   - migrate insights onto shadcn `<Tabs>` and tune `<TabsList>`
+     to honour `min-h-11`.
+   Pick one. Document.
+6. **Dialog ↔ ResponsiveSheet migration.** Audit every `<Dialog>`
+   that wraps an editable form (measurements, mood, target,
+   phase-config, research-mode, feedback-inbox dialog) and
+   migrate to `<ResponsiveSheet>` so mobile users land on a
+   bottom-sheet.
+7. **Sheet close-X parity with Dialog close-X.** Bring the Sheet
+   primitive's absolute close-X up to `min-h-9 min-w-9` with an
+   aria-label.
+8. **Mood chart YAxis `tickMargin`.** `6` → `10` to align with
+   every other line chart.
+9. **Insights/schlaf assessment slot.** Either add
+   `<InsightStatusCard>` for sleep or document the omission as a
+   primitive contract change.
+10. **Feedback-inbox mobile card-list.** Add the `md:hidden`
+    branch matching the user-management / api-token pattern so
+    `/admin/feedback` stops horizontal-scrolling on phones.
+11. **Settings account-section password form `space-y-3` → `space-y-4`.**
+12. **Empty-state `ctaSize="lg"` adoption.** Either roll out to
+    every CTA-bearing empty-state on `<sm` viewports or remove
+    from the primitive.
+13. **TrendCard's bespoke tooltip surface.** Drop the
+    `bg-muted text-foreground` override or codify as a primitive
+    variant.
+
+---
+
+## Conformity by class — bullet headline
+
+- Dashboard tiles: **two drifts** (headline `font-bold` outlier on
+  TrendCard; `bg-card/65 + backdrop-blur-sm` on 2 of 4 tiles).
+- Insights sub-pages: **one drift** (sleep skips the assessment
+  slot every other sub-page mounts).
+- Settings vs admin: **two drifts** (admin lacks landmarks + page
+  headers; admin uses `<div>` not `<h2>` for card titles).
+- Dialogs / Sheets: **three drifts** (Sheet close-X smaller than
+  Dialog; six raw Dialogs that should be ResponsiveSheets; Coach
+  drawer duplicates ResponsiveSheet).
+- Forms: **one drift** (one `space-y-3` outlier).
+- Tables: **three drifts** (feedback-inbox has no mobile card-list;
+  zebra `/20` vs `/30`; two parallel table primitives).
+- Empty states: **one drift** (unused `ctaSize="lg"` prop;
+  inconsistent size/variant on inline previews).
+- Loading: **two drifts** (spinner colour + size + motion-reduce;
+  hand-rolled skeletons bypass the primitive).
+- Buttons: **two drifts** (insights tab strip + glp1 tile bypass
+  the Button primitive; size overrides on a few revoke buttons).
+- Tab strips: **one big drift** (two completely different visual
+  languages).
+- Tooltips / Popovers: **one drift** (trend-card tooltip surface
+  override).
+- Charts: **one drift** (mood YAxis tickMargin).
+
+The codebase is internally disciplined on form rhythm
+(`space-y-4 / space-y-2`), chart axis chrome (var-tokens, no hex
+in axis fills), and the EmptyState contract — but the
+**dashboard-tile vocabulary, settings-vs-admin scaffolding,
+spinner palette, and tab-strip primitive** are the four classes
+that read least conform across the app.
