/* Dossier table: the /guides/ index rebuilt as intelligence folders cast on
   a table. Owned by the dossier lane. Copied verbatim to
   public/guides/assets/dossier.css by scripts/build-guides.mjs and linked
   from the generated pages' <head> (one <link>, nothing else added there).
   Design tokens are read from src/styles.css custom properties, which this
   file assumes are already in scope (guide.css defines :root the same way,
   so both stylesheets agree on --bg/--surface/--text/--muted/--accent/--line).

   Grammar: a folder is a single link. A tab carries the field-note number.
   A taped photo is the thumbnail. A rubber stamp carries the pack name.
   Title and dek are typed, monospace. Deterministic rotation makes the set
   read as cast on a table rather than a tidy grid; hover/focus straightens
   and lifts one folder at a time. */
