/* =====================================================================
   product-detail.css — Fair Ford Pharmaceuticals
   Premium B2B product-detail experience · productdetail.html only
   ---------------------------------------------------------------------
   Loaded after style.css (shared header/footer/cart) and
   product-marketplace.css (whose `.ffm-*` cards + rails are reused for
   the Related / You-may-also-like / Recently-viewed strips). Everything
   here is namespaced `.pdx-*`. Same palette + tokens as the marketplace
   so the two pages read as one system.

   Motion note: this project's preview engine freezes CSS-transitioned
   properties at their start value on class toggle, so anything whose
   VISIBILITY is functional (sticky bars, lightbox, gallery slide) is
   toggled without depending on a transition to reach its end state.
   Hover / decorative transitions are used freely.
