/* ================================================================
   BRIGHTME — dashboard-redesign.css  (v2)
   Scope: dashboard.html ONLY.
   A second, decisive pass on top of dashboard-premium.css:
   - Formal SVG line-icon system (no emoji glyphs in chrome/UI)
   - Refined, slightly more neutral premium palette (#2563EB)
   - True responsive grid (desktop 2-col / tablet 1-col / mobile)
   - Tighter rhythm, consistent radii & shadows across every card
   All existing IDs, classes and JS bindings are untouched —
   this file only changes appearance and layout containers.
   ================================================================ */
