/* Brief Builder page (Oct 6 2026) — every rule under .bbd / .bbd- ; colours only through tokens.css variables, so both themes work.
   It stands on the studio's own pieces (.card, .btn, .badge, .tip) and only adds layout. One column; under 640 px every button
   is a full thumb wide and the side-by-side table scrolls inside its own box (never the page). */
