   Romm Coffee — interactive 3D product viewer section.

   A deep-teal stage: the 3D Turkish-coffee bag on one side
   (drag to rotate, auto-rotates gently), story copy on the
   other. model-viewer is loaded only on pages that use it.

   Works with:
   - Pages/Index.cshtml (3D showcase section)
   - wwwroot/lib/model-viewer/model-viewer.min.js
   - wwwroot/models/turk-kahvesi.glb
