/* ============================================================================
   KILAW Student Portal — Bootstrap 5 skin ("student2")
   ----------------------------------------------------------------------------
   Loaded AFTER bootstrap(.rtl).min.css by the S2Skin component. This is the
   entire brand layer for the student2 route trees: Bootstrap 5.3 is themed
   through its CSS custom properties (no Sass rebuild), plus the `s2-*` utility
   classes for chrome the framework doesn't ship — most importantly the
   sidebar app shell (s2-shell / s2-sidebar / s2-topbar / s2-tabbar).

   Deliberately independent from apply2-theme.css so the two skins can evolve
   (and be versioned/cache-busted) separately. Brand tokens mirror
   web/tailwind.config.ts so all skins stay on-brand:
     navy  #1D2B5B (primary)   gold  #B18A3F (accent)   ink #0F172A
