/* ══════════════════════════════════════════════════════════════
   FiberOpticsTools — single-product page CSS
   Ported from docs/drafts/product-concept.html. Loads ONLY on the
   single-product template. Covers the shared two-column product
   layout and its three treatments (part / equipment / editable kit)
   plus the supporting cross-sell rails.

   Tokens, base/reset, header, footer, the docked right-rail, and the
   shared .card / .chip / .add / .tolist styles live in frame.css and
   are NOT repeated here. Light theme only — the concept's dark-mode
   token blocks are dropped.
