/* ═════════════════════════════════════════════════════════════════════
   STUDYRIA ADMIN THEME — Centralized Design System (v1.0)
   ═════════════════════════════════════════════════════════════════════
   Rebuilds the Admin App's visual layer on the official Studyria brand:
   PAPER CREAM + ROYAL MAROON + ELEGANT GOLD — premium, editorial,
   educational. Loaded LAST so it overrides the legacy dark tokens.

   ARCHITECTURE (this file is the single source of truth):
     §1  Brand tokens (the --paper/--maroon/--gold token set)
     §2  Runtime token remap — flips every token-based component
     §3  Typography & scrollbars
     §4  Shell: topbar, sidebar, navigation
     §5  Login screen
     §6  Cards & dashboard stats
     §7  Tables
     §8  Forms, inputs, selects, toggles, uploads
     §9  Buttons & badges
     §10 Modals, toasts, state states
     §11 Charts
     §12 Live Feed Notifications (sn-*) — full component system
     §13 Pagination & action menus
     §14 Mobile-first responsive overrides
