/* =========================================================================
   tokens.css — Shared design tokens for jorgemfs.com.
   Each room (home, federated-learning, blog) keeps its own layout, fonts,
   and accent, but consumes the same near-black ink, paper / dark surface
   tones, and rule colors so the site reads as one property.

   Naming: --tk-* prefix to avoid colliding with room-local custom props.
