/* ============================================================
   EVE Tools Suite — Shared Theme Tokens & Base Components
   ------------------------------------------------------------
   Single source of truth for colors, typography, spacing, radii,
   focus rings, and a small set of components (.btn, .card, .pill,
   .input, .badge, .tabbar, .tab, .toast, .banner, .empty-state).

   Apps should `<link rel="stylesheet" href="/shared/ui/theme.css">`
   FIRST, then layer their app-specific styles on top.

   Tokens use CSS custom properties on :root so they cascade to
   every element without breaking existing inline styles that
   don't yet reference them. Migration is incremental.
