 * Shared design tokens for InterAACtion Web.

 * Every custom surface we own (portal, /calibration/, /gazeplay/, the
 * gaze-bridge chrome injected into third-party apps) imports or mirrors
 * these values so the look stays consistent. The upstream apps
 * themselves (AugCom, Player, Scene) keep their own internals — we only
 * harmonise the chrome we inject on top.
 *
 * Keep this file short. Components live elsewhere.
