Subject: [PATCH] fix(ui): granular sleep sources, viewport-safe tour, one
 aligned settings language
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

A night with coarse apple-health samples next to granular watch data
showed only awake and asleep — the per-session source pick now prefers
the source that knows its stages. Tour popovers clamp into the
viewport, wrap their footer and fall back to a bottom sheet on narrow
screens. Settings and admin sections share one alignment rule — icon
column left, everything else flush on the content column — with neutral
header icons, no duplicated section titles under the shell heading, and
every select on the account-style idiom with a visible chevron. The
dashboard's customize icon matches insights, the target-settings link
leaves the home charts, and the mood heatmap adopts the damped fills
the other mood charts already use.

-### 2.7 Status indicators
+### 2.7 Section-card headers — icon column + content column
+
+Every Settings/Admin section card header follows one shape, implemented
+by `<SettingsCardHeader>` (`src/components/settings/_card-header.tsx`)
+or an equivalent inline structure:
+
+- **Icon column** (left): one Lucide icon, `text-muted-foreground h-5 w-5`.
+  Icons in card headers are always neutral — never `text-primary` or any
+  `dracula-*` accent. Purple/primary is reserved for actions and
+  highlight states (§2.8), not for iconography.
+- **Content column** (right of the icon, `gap-2` → 28 px offset): the
+  title, its description, and **everything textual that follows in the
+  card** — descriptions, follow-up headings after separators, form
+  stacks, helper/feedback lines. Apply `pl-7` to body blocks so nothing
+  textual ever starts further left than the title above it, and
+  follow-up headings align with the title column, not the icon.
+- **Exception — full-bleed structures**: data tables, tile/card grids,
+  charts, ladder lists, and `<hr>` separators may span the full card
+  width. The rule governs text alignment, not structural surfaces.
+- The page-level section `<h1>` is `sr-only`: the shell header already
+  carries "Einstellungen · <Sektion>", so a visible in-section repeat
+  is a double title. Keep the `<h1>` in the DOM for the document
+  outline and `aria-labelledby`.

- * v1.4.33 (F15) — layout-level Coach FAB contract.
+ * v1.16.1 — the layout FAB is nudge-driven now: it renders ONLY while
+ * an unseen proactive `COACH_NUDGE` exists (per
+ * `/api/insights/coach/nudge-status` + the device-local seen stamp).
+ * No permanent launcher remains — the inline pill is the everyday
+ * entry point.
  *
- * The FAB sits at the mobile bottom-right. Before v1.4.33 it overlaid
- * Recharts tooltips when the user tapped a data point in the chart's
- * lower-right corner — the maintainer flagged this as F15 in the
- * runtime audit. The fix wires the FAB to `useChartTooltipActive()`
- * which reads a singleton MutationObserver of every
- * `.recharts-tooltip-wrapper`; while a wrapper is visible the FAB
- * fades and drops `pointer-events`.
- *
- * Project convention is SSR-only tests (no `@testing-library/react`),
- * so we pin the initial-paint state — no tooltip can be active before
- * hydration, so the FAB renders without the active-flag attribute
- * and stays interactive on first paint. The end-to-end auto-hide
- * behaviour is exercised in the Playwright mobile suite.
+ * Project convention is SSR-only tests (no `@testing-library/react`).
+ * On first paint the nudge-status query has no data, so the bubble
+ * must render nothing; the unread derivation is pinned through the
+ * exported pure helper instead.

 /**
- * Layout-level mobile Coach launch FAB.
+ * v1.16.1 — the layout FAB is no longer a permanent launcher. It now
+ * renders ONLY while an unseen Coach-initiated nudge exists (the
+ * proactive `COACH_NUDGE` dispatch, surfaced by
+ * `/api/insights/coach/nudge-status`): a floating circle at the bottom
+ * right that opens the full-page Coach chat. It disappears once the
+ * nudge counts as read — the user sent a Coach message after the
+ * nudge (server-derived), or opened the Coach on this device (local
+ * seen stamp keyed by the nudge timestamp).
  *
- * v1.4.28 R3c — promoted out of `<CoachLaunchButton>` (which previously
- * rendered both the FAB and the inline pill from a single component;
- * each sub-page mount therefore painted a duplicate FAB into the DOM
- * before `fixed` positioning collapsed them visually). Mounting the
- * FAB once at the layout level keeps the affordance reachable from
- * every routed Insights surface while leaving the a11y tree with a
- * single button.
+ * The previous always-on mobile FAB drew attention to nothing; the
+ * inline "Ask Coach" pill in each page's action row stays the everyday
+ * entry point.
  *
- * Hidden on `lg+` viewports — desktop users reach the Coach via the
- * inline `<CoachLaunchButton>` pill that each page mounts in its
- * action row.
- *
- * v1.4.33 (F15) — the FAB sits at `bottom-right` and used to overlay
- * Recharts tooltips on the bottom-right of any insight chart, so a
- * mobile user tapping a data point near the chart's lower-right
- * couldn't read the bubble. The button now auto-hides while a chart
- * tooltip is active (the wrapper's `visibility: visible` flips us
- * to fade-out + pointer-events-none). When the user releases / scrolls
- * away the tooltip clears and the FAB fades back in.
+ * v1.4.33 (F15) — the bubble keeps the chart-tooltip auto-hide so it
+ * never overlays a Recharts tooltip on the lower right.
