/* ---------------------------------------------------------------------------
   Product detail page (/devices/{slug}).

   Manufacturer-style layout: a large image with thumbnails on one side, the
   name, headline claims and the buy controls on the other, then the long
   description, the full spec table and related products underneath.

   Uses site.css tokens only, so it follows the light/dark toggle. Logical
   properties throughout so RTL mirrors itself. Never a bare .card selector.
