   FiberOpticsTools — catalog / shop page CSS
   Ported from docs/drafts/catalog-concept.html. Loads ONLY on the
   shop/catalog page. Composes the shared tokens + component patterns
   defined in frame.css — do NOT redefine tokens, base/reset, header,
   footer, cards, or the contextual right-rail here.
   Single light theme (values inherit from frame tokens).
