   DSAlpha Site Theme Tokens
   ─────────────────────────
   Every visual surface reads from CSS custom properties defined here.
   Each theme block must declare the full token set so pages render
   identically regardless of which theme is active.

   color-scheme is set per-theme so native form controls (scrollbars,
   date pickers, etc.) match the palette automatically.
