/* product.css — the graph-driven catalog detail page (server/templates/product.html).
   Loaded ONLY on those routes via PageData.PageCSS, so the 377 other pages do
   not pay for it. Tokens come from site.css; nothing here redefines a variable.

   Two layout invariants, both gate conditions in .claude/pm/80-qa:
     · no horizontal overflow at any width — every rail scrolls inside itself
       and every grid column is minmax(0, …) so a wide image cannot push the
       page wider than the viewport.
     · nothing depends on JS. The zoom is an <a href> that works when
       assets/js/product.js never loads. */

/* ── hero ─────────────────────────────────────────────────────────────────── */
/* The slab spans the FULL viewport width and the facts sit underneath it. It
   was a 1.25fr column beside a text column, which capped the slab at ~660px on
   a 1600px screen — the one image a countertop shopper actually wants to
   inspect, shown smaller than the text next to it. Full-bleed via 100vw with a
   negative margin, not by escaping .wrap, so the surrounding layout is
   untouched. calc(100vw - …) accounts for a scrollbar; without it the page
   gains ~15px of horizontal overflow, which is a gate failure. */

   scrollbar, so on a page tall enough to scroll it is ~8-15px wider than the
   content box and the page gains that much horizontal overflow — measured at
   exactly 8px here, and "no horizontal spill, ever" is a gate condition.
