/* Hallmark · pre-emit critique: P5 H5 E4 S5 R5 V5
 * Hallmark · macrostructure: Sidebar Filter · genre: atmospheric · theme: Dusk (system-managed, design.md)
 * page: Catalog (home) · nav: N10 scroll-morph (design.md) · footer: Ft4 dense colophon
 *
 * Persistent facets on the left, results on the right. The facet counts double
 * as the distribution chart — same numbers, one surface, so there is no second
 * "stats" section restating what the sidebar already shows.
 * Imports tokens.css and base.css; adds only catalog-specific rules.
