/* ============================================================
   ALDEAPATH — Unified Notification & Feedback System
   ------------------------------------------------------------
   One canonical visual language for every message the user sees:
   toasts, inline form validation, page-level banners and the
   branded error screen.

   Tokens come from aldeapath-system.css (--success / --danger /
   --warning / --info / --card / --border / --text / --muted).
   Fallbacks are provided so this file also works standalone on
   pages that do not load the full design system.
