/* ============================================================================
   Firmify.ai · Design System (app.css)
   Shared tokens + app-shell layout + reusable components.
   "Accounting-grade": calm, professional, trust over flash.

   PREMIUM POLISH PASS:
   - Dual theming via :root (light) + :root[data-theme="dark"] (dark) token
     overrides. EVERY component references tokens, so the whole app re-themes
     automatically. Existing token + class names are PRESERVED (never removed
     or renamed), only added to and enhanced.
   - Glassmorphism on sidebar/topbar, layered card depth + lit edge, ambient
     floating gradient blobs, tasteful micro-interactions, theme-aware styled
     scrollbars. All non-essential motion is gated behind prefers-reduced-motion.
