   White, hairlines, dot grid. Inter light display + Roboto Mono spec labels.
   Part 1 is a copy of the product-UI kit (assets/shared/product-ui/kit.css:
   tokens, primitives, recorder, editor, script, captions), without its local
   @font-face rules (Chromium blocks them on file://) and with asset paths
   rewritten for this folder. Inter and Roboto Mono load from Google Fonts.
   Part 2 is the V3 page system.
