/* ─────────────────────────────────────────────────────────────────────────
   DARKROOM — the Reference section. Loaded after cc.css by both of its pages.

   The umbrella's cards and the family index's rows. The rows are this sheet's
   own `.rfr` rather than cc.css's `.rr`: the ledger row is a version, a date
   and two counts, and this one is a name, a line of prose and two markers, so
   sharing the class would have meant one of them overriding four rules of the
   other on every page.
   ───────────────────────────────────────────────────────────────────────── */

/* Top padding only. `.ref` sits on the same element as `.shell`, and a padding
   shorthand here has equal specificity and loads second, so it would wipe
   `.shell`'s `padding:0 var(--pad)` and run the page 80px wider than the
   masthead above it. DarkroomAssetsTest fails on the shorthand. */
