   recodeai — design system (2026 rebuild)
   Ported verbatim from the approved prototype bundle (Modernist tokens).
   Source of truth for the look of: / · /firehouse · /diagnostic · /faq

   NOTE: assets/recodeai.css is the OLD warm-palette system still driving
   /explain, /memos and generated pages. Do not merge the two. See
   PLAN-recodeai-rebuild.md §8.

   Two halves:
     PART 1  tokens + component classes (verbatim from the prototype)
     PART 2  page composition + a compatibility shim for the classes that
             agents/update_agent.py injects, so the daily firehose HTML
             renders in this design with ZERO changes to the agent.
