/* =====================================================================
   Shikshanetra design system — sn-theme.css
   Owner: UI-01. Ported from the production portal theme
   (portal/assets/css/global-theme.css, modal-fixes.css, modules/auth.css)
   with every brand colour moved into CSS variables so each tenant can
   override them (layouts print a nonce'd :root{--sn-primary:…} block).

   Load order: fonts.css → bootstrap.min.css → fontawesome → sweetalert2
               → sn-theme.css → sn-sidebar.css (app shells) → sn-dark.css

   Deliberate differences from production (WCAG 2.1 AA, see README):
   solid/gradient success, warning, info and danger fills are one shade
   darker so white text reaches 4.5:1; muted text uses slate-500 (#64748b)
   instead of slate-400.
