test(insights): coverage for v1.4.19 polish changes

Source-grep guards for the four /insights polish concerns Marc
flagged on 2026-05-10 plus drift guards for the chart-token leak
fix:

  1. Dashboard does NOT mount <CompareToggle /> — the import +
     JSX use are both gone. Drift guard verifies
     `comparisonBaseline` / `compareBaseline` plumbing still
     reaches the charts (only the on-surface affordance moved).
  2. /insights renders exactly ONE `onRegenerate={advisor.regenerate}`
     prop — the page hero. The advisor card's duplicate handlers
     are gone.
  3. /insights does NOT mount <TrendCard> — the duplicate-of-
     dashboard tile strip. Verified via the import path being gone
     and any JSX-style mount being absent.
  4. /insights does NOT pass `t("insights.aiOverviewTitle")` as a
     subtitle — the orphan "Persoenlicher Berater" placeholder is
     gone.
  5. `stripChartTokens()` cleaves lowercase + mixed-case AI
     emissions; `parseChartTokens()` stays strict (uppercase
     allowlist only).

Source-grep tests rather than full React renders so they don't
pull in the dynamic-imported charts + advisor query stack the page
mounts. The cost is a slight false-positive risk if a future
refactor renames the JSX literal we're matching, but the comments
on each test point at the load-bearing assertion so a renamer can
update the guard without losing the contract.

+# Phase A6 — Settings mobile audit + consistency
+
+**Owner:** A6 agent (Wave A, parallel with A1-A5, A7-A8)
+**Date:** 2026-05-10
+**Result:** done
+
+Audit findings and the fix plan live in
+[`.planning/phase-A6-settings-audit.md`](./phase-A6-settings-audit.md).
+The audit is keyed to `before/` screenshots captured against
+`https://healthlog.bombeck.io` at Pixel-5 (393×851) using Marc's
+session cookie; raw geometry was extracted with
+`scripts/audit-a6-v2.mjs` to spot the height mismatches the
+human eye missed.
+
+## What was wrong
+
+- **Four input heights in the same shell.** The shared `<Input>`
+  primitive renders at 36 px (`h-9`) but Settings broke the contract
+  at three points: the AI active-provider native `<select>` was
+  `h-10` (40 px), the AI fallback-chain "Add provider" select was
+  `h-8` (32 px), and the Dashboard "Compare to" `<SelectTrigger>` was
+  `min-h-11` (44 px). Visible whenever two cards stacked on top of
+  each other.
+- **Action-button overflow.** "Restart onboarding tour" lived in a
+  `flex justify-between` row next to its card title. On Pixel-5 the
+  button (216 px wide) overflowed the right edge of the parent card
+  by ~48 px because nothing forced a wrap. The "Change password"
+  button used the same pattern and was on the borderline.
+- **Sprache buried.** The locale switch was paired with date-of-birth
+  inside the Profile card grid, implying it was a profile attribute
+  (it isn't — it's a cookie-backed UI preference).
+- **Three competing `space-y-*` strides** inside Settings cards
+  (`space-y-3`, `space-y-4`, `space-y-5`) — outer rhythm was already
+  `space-y-6` consistently.
+
+## What was fixed (5 commits)
+
+1. `957f8e9` — `fix(settings): equalize input heights across all
+   settings sections`. AI active-provider select `h-10` → `h-9`, AI
+   add-provider select `h-8` → `h-9`, Dashboard "Compare to" trigger
+   loses `min-h-11` so the default `h-9` applies.
+2. `9fda634` — `fix(settings): action-button placement consistent
+   across sections (right-side desktop, stacked mobile)`. Account →
+   Password, Account → Restart onboarding tour and Dashboard → Reset
+   to defaults all use `flex-col` on `<sm` and `flex-row` on `>=sm`,
+   so the button stacks below the title on mobile (full-width) and
+   right-aligns next to the title on desktop. Description paragraph
+   pulled into the title cluster on the two account cards so each
+   row is a clean `<title-block + button>` flex pair.
+3. `1075784` — `fix(settings): Sprache select position + width
+   consistent`. Language lifted out of the dob/language pair into
+   its own row at the bottom of the Profile card. `max-w-xs` on
+   `>=sm` so it doesn't render heavier than other half-width fields.
+   Drive-by: pulled the duplicated native-select class string into a
+   single `NATIVE_SELECT_CLASS` constant so gender + language render
+   identically.
+4. `737b533` — `style(settings): uniform vertical spacing across all
+   sections`. Dashboard layout card `space-y-5` → `space-y-4`. AI
+   provider config forms `space-y-3` → `space-y-4`. Section roots
+   keep `space-y-6` so distinct cards still read as distinct
+   surfaces. Note: `.planning/STATE.md` got bundled into this commit
+   accidentally via index race with A5; STATE content is correct,
+   no semantic harm.
+5. `78f1f3f` — `test(settings): mobile e2e snapshot verifies
+   consistency`. Pixel-5 Playwright spec
+   (`e2e/settings-mobile-consistency.spec.ts`) locks in five
+   invariants: every form input on /settings/account is 36 px,
+   neither password nor tour buttons overflow the card right edge,
+   Sprache and dob no longer share a grid ancestor, the Dashboard
+   "Compare to" trigger is 36 px, every native select on
+   /settings/ai is 36 px. Mobile-only project — desktop skips it.
+
+## Verification
+
+- `pnpm test` — all 1637 tests pass
+- `pnpm typecheck` — zero source-tree errors (the four `.next/types`
+  errors are stale build artefacts from previous milestone's untracked
+  dotted-segment route directories, documented in CLAUDE.md / STATE.md
+  as Phase 0 leftovers)
+- `pnpm lint` — zero errors, 12 pre-existing warnings unrelated to A6
+
+A post-fix Playwright re-screenshot pass against production is gated
+on the v1.4.19 deploy (Phase E). The new e2e spec is the durable
+artifact and runs on every PR.
+
+## What I deliberately did NOT touch
+
+- `src/components/settings/integrations-section.tsx` (A5 owned and
+  shipped during this phase as commits `0dcc91a` + `47a8fc7`).
+  A prettier autofix bundled two trivial reformats of A5's files
+  into my draft "uniform spacing" commit; those reformats were
+  reverted before the final commit landed.
+- `src/components/admin/*` (A7).
+- `src/lib/insights/`, `src/lib/ai/`, `src/components/charts/`,
+  `src/components/insights/` (A1-A4).
+- Any settings copy or i18n keys — the focus stayed on layout, sizing,
+  and spacing per the brief.
+
+## Files touched
+
+- `src/components/settings/account-section.tsx`
+- `src/components/settings/ai-section.tsx`
+- `src/components/settings/dashboard-layout-section.tsx`
+- `e2e/settings-mobile-consistency.spec.ts` (new)
+- `.planning/phase-A6-settings-audit.md` (new — findings table)

+## Inconsistency table
+
+### Input heights
+
+| Section       | Element                             | Actual | Expected |
+| ------------- | ----------------------------------- | -----: | -------: |
+| account       | Username `<Input>`                  |     36 |       36 |
+| account       | Email `<Input>`                     |     36 |       36 |
+| account       | Gender native `<select>`            |     36 |       36 |
+| account       | Height `<Input type=number>`        |     36 |       36 |
+| account       | Date of birth `<Input type=date>`   |     36 |       36 |
+| account       | Language native `<select>`          |     36 |       36 |
+| ai            | "Active provider" native `<select>` | **40** |       36 |
+| ai            | "Add provider" native `<select>`    | **32** |       36 |
+| dashboard     | "Compare to" `<SelectTrigger>`      | **44** |       36 |
+| export        | All date `<Input>` fields           |     36 |       36 |
+| notifications | All telegram + ntfy `<Input>`       |     36 |       36 |
+
+The account section is internally consistent at 36 px. AI and Dashboard
+break the 36-px contract: the AI active-provider select is 40 px, the
+fallback "Add provider" select is 32 px, and Dashboard's "Compare to"
+trigger uses `min-h-11` (44 px). All three are form fields the user
+fills with their finger, so they should match the rest of the app.
+
+### Action-button placement
+
+| Section       | Button                          | Placement on mobile      | Overflow?                         |
+| ------------- | ------------------------------- | ------------------------ | --------------------------------- |
+| account       | Save (profile)                  | bottom of form, right    | no                                |
+| account       | Add passkey                     | bottom of card, right    | no                                |
+| account       | **Change password**             | inline next to title     | borderline (336 / 361)            |
+| account       | **Restart onboarding tour**     | inline next to title     | **YES — overflows card by 48 px** |
+| ai            | Disconnect                      | full block, sm           | no                                |
+| dashboard     | Reset to defaults               | inline next to title, sm | no                                |
+| export        | Configure & generate / Download | bottom of card, sm       | no                                |
+| notifications | Send test (status card)         | inline                   | no                                |
+
+Critical bug: on a 393-px viewport the "Restart onboarding tour" button
+overflows the right edge of its parent card by ~48 px. The same flex
+pattern (`flex items-center justify-between gap-2`) is used by the
+password-reset card; with longer button copy it crosses the card edge.
+
+### Spacing inconsistencies
+
+| Section       | Section-level spacing | Card-internal spacing                         |
+| ------------- | --------------------- | --------------------------------------------- |
+| account       | `space-y-6`           | `space-y-4` (form), `space-y-2` (field group) |
+| dashboard     | `space-y-6`           | `space-y-5` (card), `space-y-2` (field group) |
+| ai            | `space-y-6`           | `space-y-6` (card), `space-y-3` (sub-card)    |
+| notifications | `space-y-6`           | per-card varies                               |
+| export        | `space-y-6`           | `gap-3` grid + `mt-3 space-y-3` (card)        |
+
+The `space-y-6` outer rhythm is consistent; the card-internal rhythm
+varies between `space-y-3` / `space-y-4` / `space-y-5`. Visible because
+the AI card crams its sub-cards with `p-4` while the Account card uses
+`p-6` — equivalent fields end up at different distances apart between
+sections.
+
+### Sprache-Menü specifics
+
+The Sprache (language) `<select>` lives in the same row as the date-of-
+birth field on the Account → Profile form. Both render at 36 px on
+mobile, so technically consistent — but the Sprache field is paired
+with a row that already carries a hint paragraph below the date field,
+which makes the column heights asymmetric. On `<sm` the grid collapses
+to a single column so the visual order becomes:
+
+date-of-birth → date-hint → language → language-hint
+
+That ordering is fine, but the Language field is the only locale switch
+in the entire settings shell. It is buried halfway down the Account →
+Profile card next to "date of birth", a profile attribute. Visually it
+feels like part of the profile (it isn't — it's a per-session UI
+preference stored in a cookie, not the `users.locale` column).
+
+### Dashboard "Compare to"
+
+Renders at 44 px (`min-h-11`) which mismatches the 36-px input contract
+elsewhere. The 44-px tap-target floor matters where the only mobile-
+nav action is a tap, not where the input lives inside a longer form
+the user is already engaged with. Bring it down to 36 px on `>=sm`.
+
+## Decisions
+
+1. **Standardise input height to 36 px** (`h-9`). Replace the 40-px
+   ai-active-provider select, the 32-px add-provider select, and the
+   44-px comparison trigger with the shared 36-px contract.
+2. **Mobile action-button rule**: when a card's title and an action
+   button live on the same row, the button stacks below the title on
+   `<sm` (full-width) and right-aligns next to the title on `>=sm`.
+   Prevents the "Restart onboarding tour" overflow.
+3. **Card padding rule**: every settings card uses `p-6` (or `p-5` for
+   sub-cards inside a parent card) — pick one. Settled on `p-6` for
+   top-level cards. The AI sub-card uses `p-4` which matches its
+   nested role; left as-is.
+4. **Sprache placement**: lift out of the dob/language pair into its
+   own row at the bottom of the Profile card. Keeps copy as-is, but
+   stops implying language is a profile attribute.
+5. **Spacing**: top-level section uses `space-y-6`. Card-internal
+   spacing standardises on `space-y-4` between blocks; `space-y-2`
+   for label + input pairs.
