/* ---------- specdec-findings additions (2026-10-20, revised 2026-10-21) ----------
   Appended by build.py after src/scriptorium.css, which is kept byte for byte as chosen;
   build.py also applies the listed replacements to it (README.md, "Stylesheet"): the three
   face tokens come from src/faces.json, and the four italic declarations are removed.
   Layout rules from plan 16.9/16.10: provenance chips wrap, and every grid track that can
   grow is minmax(0, 1fr), so a long chip cannot widen a card over its neighbour. The
   auto-fit column counts of the prototype are kept as media queries at the widths where
   auto-fit changed its count (content width = viewport - 32px, capped at 1080px). */
