/* The Roman Era — imperial skin layered over the parent gallery stylesheet.
   Same pattern as napoleon.css: style.css supplies the whole component system;
   this file only re-tunes tokens (Tyrian purple + bronze gilt instead of the
   Empire's crimson) and carries the bespoke pieces — collection bar, laurel
   SPQR cypher, the dek. Everything stays on the parent's type scale, spacing
   rhythm and easing so the collections read as one site. */
