/* TripAgenda — the Now Bar + Active HUD (IA_v1 §4a, Stage C Task 9).
   Docs: IA_v1.md, BRAND_v1.md
   The app's signature interaction: a context-aware bottom bar that reflects
   the current itinerary moment (computed, offline-safe), morphs as the day
   advances, and swipes up into a full-screen thumb-tile HUD. SOS lives ONLY
   in that HUD. Token-driven; documented exempts only:
     • accent ring rgba(245,135,10,.18) — the established pulse-dot ring
     • iOS system red #FF3B30 — the SOS tile (system-canonical danger colour)
     • soft shadows (non-semantic depth) */
