   Source-of-truth for tokens: src/app/globals.css in the publisher
   repo. Keep this file in lockstep with that file when palette /
   typography tokens change.

   Pass 1 scope: chrome (header, footer, body backdrop) + post-page
   container. No homepage cards, no BorderGlow, no topic indexes —
   those land in pass 2.

   Post-page chrome — minimal because research artifacts ship their
   own hero (kicker, title, lede, stats line) inside the HTML card.
   The theme provides only:
     1. A thin breadcrumb at the top — navigation context.
     2. A conditional feature image — renders when set in Ghost
        admin per-post, does nothing when unset. Operators leave
        this unset on artifact-format posts whose own hero would
        otherwise compete; they set it on Ghost-native blog posts
        and so that listing-view cards (homepage / topic indexes)
        have a thumbnail regardless of detail-page rendering.
   Title, excerpt, date, reading time are intentionally omitted to
   avoid redundancy with the artifact's own hero band.
