/**
 * PUBLIC CATALOG — THE BROWSE SURFACES: the landing hero and its sections, the
 * category grid and .cat-card (including the generated fallback art a category
 * with no thumbnail falls back to), the admin-only bulk vault toolbar, and the
 * file grid with its per-width overrides.
 *
 * FOURTH of ten sheets — after styles-page.css, before styles-detail.css. Read
 * the load-order block at the top of styles.css before moving a rule between
 * sheets: the split is a contiguous slice of one original file and the cascade
 * depends on it.
 *
 * The 980px and 640px file-grid blocks are at the BOTTOM OF THIS FILE, where
 * they were in the original, so one surface's sizes stay in one place.
