/* ------------------------------------------------------------------------
   Manifest storefronts - shared shop chassis.

   Structure only: rhythm, controls, product cards, checkout. Each shop sets its
   own identity layer (palette, type, texture) in its own <style> block, because
   the whole premise is three unrelated businesses. Nothing here should make them
   look like siblings.

   Radius rule for every shop: 0 on surfaces, full-pill on interactive controls.
   One system, applied everywhere.
