/* =====================================================================
   School ERP - Design System  (v2 - "Premium" re-skin)
   ---------------------------------------------------------------------
   A Bootstrap-5-based, mobile-first SaaS dashboard skin: sidebar +
   topbar shell, cards, form sections, tables, modals.

   v2 notes: this is a pure *visual* re-skin. Every class name from v1
   is preserved (many views set `style="--icon:#.."` inline and rely on
   `var(--brand-*)`), so nothing in the 55 view modules had to change -
   only the values, the spacing rhythm, the shadows/radii, the form-
   section treatment and the component polish were lifted toward a
   cleaner, calmer look. New optional components (.page-header,
   .form-section, .chip, .section-label, .detail-list, .toolbar,
   .lang-switch) are additive - old markup keeps working untouched.

   Palette direction borrowed from a reference offline school app:
   deep institutional navy, a brighter azure for anything interactive,
   a warm saffron accent used sparingly, calm blue-grey surfaces.
