   FORGED CARBON — SUBPAGE DESIGN SYSTEM
   --------------------------------------------------------------------------
   The subpages (forge-12, use-cases, story, certifications, contact) were
   authored against a token + component system that was never shipped. This
   file supplies it. Dark, editorial, premium — built to convert.
   Loaded AFTER css/styles.css on subpages only; the homepage never loads it,
   so its light theme is untouched.
