/* ============================================================
   Stocky — Briefings (spec 08)
   Layered on colors_and_type.css + components.css. Reuses the
   .digest card; adds day grouping, ticker-move chips, card
   actions, and three layout scaffolds (feed / timeline / hero)
   so the periodic LLM digest has a real home at /briefings.
   No invented colors or radii — DS tokens only.
