/* ============================================================
   NATION NEWS HINDI — SHARED DESIGN SYSTEM
   Loaded by every public page via includes/head.php. Bootstrap
   5.3 utility classes (d-flex, container, row/col, etc.) are still
   used throughout the markup — this file layers a premium,
   "hitech SaaS" visual language on top of them rather than
   replacing Bootstrap outright, so existing markup keeps working.

   Both themes are CSS custom properties on :root / [data-theme],
   matching the toggle script already used on every page (dark by
   default, [data-theme="light"] override, localStorage-remembered).
