+## [1.5.15] — 2026-05-19
+
+### Accessibility
+- **Fix WCAG AA contrast on active filter chips (History + Report)** — active chips used `#ee2c80` (magenta) fill with white text at 3.95:1, failing WCAG AA for normal text (requires 4.5:1). Added `--accent-active: #b5116a` token (~6:1 with white) to `carbon-tokens.css` and updated the active chip `background` and `borderColor` in `History.jsx` and the `FilterChip` component in `Report.jsx` to use it.

 - `Report.jsx` → `SectionLabel` eyebrow with period + active day filters on two separate `display:block` spans; three separate `flexWrap: wrap` filter rows (period / weekdays / session types) with `1px solid var(--border-subtle-wl)` top borders between groups; "Nullstill filter" always rendered (opacity-toggled); KPI tiles → heatmap body → hover detail → heat legend → frequency table → gap callout card (with `AccentChip` per untrained muscle) → recommendation button → recs list; when all primary muscles trained shows positive fallback message; when some muscles secondary-only shows those as blue tags; recommendation rows have 3px accent left strip + round `+` button that saves the exercise inline via `saveLibraryExercise`; "Oppdater anbefalinger" ghost button (`Renew` icon) below the recs list — re-runs Claude call and overwrites the cache entry; no `StickyCta`; recs are persisted in the shared `recommendation_cache` Supabase table (see data model) and restored on mount/filter-change via `fetchRecsCache`; prefill prop applied on mount via `useRef` — supports `periodDays`, `selectedDays`, `selectedTypes`, `weekday`, `sessionType`; `KpiTile` (42px Plex Light value); `muscleLastDate` in useMemo
 - `PageShell.jsx` → exports: `SectionLabel` (mono 12px, 0.16em tracking, 3px `var(--accent)` left border; accepts optional `renderIcon` prop — renders the Carbon icon at 14px before the label text), `PageHeading` (Cond 700 28px), `PageTitle` (alias for SectionLabel), `AccentChip` (magenta pill: `var(--accent-bg-14)` bg, `var(--accent-soft)` text), `StickyCta` (sticky bottom bar with top border), `BackButton`; `NavBtn` is a `forwardRef` component accepting `l1` and `l2` props — renders a 2-line Plex Condensed (8px) label below the icon; nav bar height is 56px; nav icons in order: Camera → RecentlyViewed → Analytics → EventSchedule (Planlegger) → Notebook (Sett-sammen) → Settings — 6 icons each 48px wide; theme toggle and logout removed from header (now in Settings view); `ChangelogModal` no longer rendered here. `useNavHints` moved to `app/src/lib/hooks.js` (issue #253)

 - `app.css` → global `html, body { overflow-x: hidden }` to prevent horizontal viewport bleed from chip rows; do not use `overflow: hidden` on direct parents of `flexWrap: wrap` chip containers — it clips instead of scrolling
 ### Hard rules (must not regress)
 - **Sentence case** for all labels — `Add exercise`, not `Add Exercise`
