/* ==========================================================================
   Coco's, Dereham (outreach demo)
   One lead effect: a steaming cup of coffee in the hero, in real 3D where the
   device allows (cup3d.js), an animated SVG everywhere else.
   Everything else supports it: a printed menu with depth, reviews pinned up
   like notes, a live "open now".
   Espresso, white and one egg-yolk yellow. Mobile-first. Light + dark.
   No framework, no build step. WCAG 2.2 AA.
   ========================================================================== */
