/**
 * Amari Calendar — canonical booking calendar + time-slot UI.
 *
 * Source of truth for visual language. Documented in SYSTEM.md.
 * Prefer classes with the `am-cal-` / `am-slot-` prefix.
 * Legacy public-page aliases (`.cal-*`, `.slot-btn`, `.time-slots*`) are kept
 * so /book/* pages can link this file without renaming markup yet.
 *
 * Token fallbacks map onto site-v6 (--cream/--ink) and portal (--cp-*).
