   One shared sheet for index.html + legal pages (privacy/terms/impressum).
   Semantic token system derived from a single brand blue (#2B6BEE).
   A `.theatre` scope remaps the SAME tokens to a near-black ink-blue canvas,

   No second hue. No blue→purple gradient. Motion is transform/opacity only.
