/* V52-002 (EXP52/v1.0) -- Explore models gallery (/Catalog, /categories/{slug}). SCOPED ONLY: every rule starts with .pb52x
   (Views/Catalog/Index.cshtml); no element / global selector, no change to the shell, header, sidebar or the shared cards.
   Existing PB tokens only (Light / Dark / System through pb-tokens.css); logical properties (RTL / LTR flip once); 48px touch
   targets; no animation. Two compact rows (categories; sort / period / filters) of 48px + one 8px gap = 104px before the grid;
   at 200% text the rows may reflow (no clipping). The category row scrolls inside itself, never the page. */
