   PRODUCT PAGE — shared UI, cloned from screen.studio
   ────────────────────────────────────────────────────────────────────────
   Loaded FIRST; each product's theme.css loads after and overrides only its
   brand tokens (accent, surfaces). Structure never hard-codes a value — it
   reads variables, so swapping theme.css re-skins the page (VS Code model).

   Values measured from screen.studio's shipped CSS: type scale 96/62/24/18/
   16/13 at weights 650/450, 50px pill radius, entrance bezier
   cubic-bezier(.37,2,.42,1.02), system font stack, #000 ground, #13151B card.
