/* ============================================================================
   Baybos Console — shared design system for the school operating systems.
   ONE dark, premium, minimal language across every back-office tool.

   How it drops in:
   • Tool pages already reference var(--bg), var(--card), var(--accent)… etc.
     This file DEFINES those exact names with refined values, so linking it and
     deleting a page's own :root re-skins that page consistently — no markup churn.
   • Component classes are namespaced .bx-* so they never clash with a page's
     existing .card / .btn rules. New work should prefer the .bx-* components.

   Palette identity: deep navy-black canvas · violet primary · gold brand warmth.
