/* ══════════════════════════════════════════════════════════════════════════
   final/css/pdp.css — LANE 21. THE PRODUCT PAGE, RE-COMPOSED.

   Owner reference (2026-08-26): a competitor PDP, taken for STRUCTURE ONLY.
   That reference is a white ground with a purple accent; every colour below
   resolves through this client's own solved tokens, so the page ships DARK
   NAVY + the client's accent and never the reference's palette.

   SCOPING. lib.linkCss() links this sheet on EVERY page, so anything that is
   not `.pdp-*` is scoped under `#product-main` — the id only product.html
   carries. `.qty-btn`, `.vol-card`, `.rel-card` and `.research-warn` all exist
   on other surfaces of this store and must not be repainted from here.

   THE IMAGE PLATE STAYS LIGHT ON PURPOSE. sf-refresh.css pins
   --sf-photo-bg: #FFFFFF and forces #ruo-overlay's ink to navy-900 because the
   vial photographs are shot on white. This sheet gives the plate its radius,
   its padding and its ring and NEVER its background — painting it dark would
   put a white-cut vial on a dark square and drop that overlay to ~1:1.
