/* ═══════════════════════════════════════════════════════════════════════
   GROUP NOTICEBOARD — the feed  (css/23, Prompt 58)
   ─────────────────────────────────────────────────────────────────────
   A calm, cross-hotel announcement feed staff enjoy opening. Deliberately a
   CARD FEED — not the collection-browser shell (a feed is time-ordered
   content, not a library, pack header line 10). It reuses the app-wide
   chrome wherever one exists:
     • month folds  → the Tasks `.tasks-month-*` classes (css/05) verbatim
     • buttons      → `.tasks-btn` / `.tasks-btn-secondary` (css/05)
     • site chip    → `.card-loc-chip` (css/04)
     • empty/error  → `.asset-empty` (css/13) + AngelHubUI.loadErrorHtml
   so this file only styles what is genuinely new: the post card (two-tier
   law), the 16:9 photo hero, the calm category chip (accent on the ICON
   only), the pinned strip, the "N new" chip, and a minimal read-only detail
   sheet (Prompt 60 replaces the sheet body with the full P31 detail).

   Both themes ride the shared tokens (no literal colours). Mobile full-width
   overrides live at the END of the file (source order — §4). No hover-only
   controls; visible focus rings; motion respects prefers-reduced-motion.
