/* ============================================================
   components.css — the atomic component library.
   100% driven by the token contract (see _contract.md).
   Every skin is a value-swap: change tokens.css, not this file.

   Rules:
   - No literal colors / font-families / radii here (only var(),
     currentColor, transparent, inherit).
   - Optional/effect tokens are read with a fallback so an
     undefined token is a no-op, not a broken property.
   - [data-surface="reversed"] remaps the FULL role set incl.
     button aliases, so inverted grounds stay legible.
   ============================================================ */

   that sits on an inverted ground. Each companion falls back to
   its base role when a skin doesn't define it. */
