/* ============================================================
 * StudentCenter — shared stylesheet (REDESIGN 2026-07-10)
 * ------------------------------------------------------------
 * Design source: DESIGN-SYSTEM.md (StudentCenter-redesigned zip)
 * + the z.ai preview. Every class name/token from the previous
 * stylesheet is preserved so all pages keep working; new
 * components (sidebar/topbar, avatars, stat cards, steps,
 * milestones, video grid, split login) are added on top.
 *
 * Golden rules (from DESIGN-SYSTEM.md):
 *   - tokens ONCE in :root, consume via var()
 *   - every shadow = 2 layers (near dark + far primary glow)
 *   - active buttons = gradient + colored glow, hover lift
 *   - badges = dot + light bg + dark fg + translucent border
 *   - NO black backgrounds
 *
 * Sections:
 *   1.  Fonts
 *   2.  Design tokens (:root) — new scale + legacy aliases
 *   3.  Reset + global + ambient background
 *   4.  Layout helpers
 *   5.  App shell: sidebar + topbar
 *   6.  Buttons
 *   7.  Badges
 *   8.  Inputs
 *   9.  Cards + page head
 *   10. Tables (SmartTable) + inline editors + avatars
 *   11. Pagination
 *   12. Modal / dialog
 *   13. Legacy top nav (kept for compatibility)
 *   14. Stat cards + sparkline
 *   15. Icon containers + PNG icon tints
 *   16. Activity feed
 *   17. Video grid
 *   18. Upload steps + progress + milestones
 *   19. Login (split screen)
 *   20. Empty state + toast
 *   21. Utility classes
 *   22. Animations
 *   23. Responsive
