/* ============================================================
   ALEX UI — styles.css (v1, final-form foundation)
   ------------------------------------------------------------
   Philosophy:
   - Tokens first (colors, spacing, type, radius)
   - Components are single-class with optional modifiers
   - Layout uses a few primitives (container, stack, grid)
   - Utilities for quick tweaks, but keep them minimal
   - Works for both Landing + Dashboard (App)
