/* commerce/03-open-desk/skin.css — P03 Open Desk persona skin (component SK-A).
   Hand-authored by SK-A-P03-skin-builder. Overrides commerce/base/flow.css (loaded first).
   Tokens/geometry from samples/03-open-desk/index.html (:root lines 16–35, masthead 114–170,
   sheets 294–311: thick teal top rule + soft blurred shadow). Light-only persona: the base dark
   scheme is overridden so the warm paper survives prefers-color-scheme: dark (no forced flip).
   Structural flags on <body>: data-skin-catalog="cards" data-skin-breakdown="beat"
   data-skin-density="calm" data-skin-nav="none" data-skin-scheme="light".
   R5 §11: only type, colour, geometry, layout, density, responsive transformation, chrome. */
