   when you Frankenstein after the fact, it tends to struggle"). The look of a demo is DESIGNED PER DEMO in its own
   app.css from the buyer's site (palette + logo + their screenshot: protokit.py theme), PROTOTYPE.md s5.

/* LAYER 3: THE LOOK PIECES. Pulled from the Wave demo (projects/wave/code/api/wwwroot/app.css, 11-10, 0 axe violations
   on 96 views). Neutral greys underneath; the BUYER'S COLOURS go on top through the brand + accent tokens below,
   written by `protokit.py theme DIR --from <buyer url>` into DIR/theme.css (Rob 11-10: "use their colors"). Never their logo.
   SUPERSEDED (Rob 11-10 ~1:55 PM ET): "a neutral palette: never the buyer's logo or colours ... a demo may change ONLY
   --accent". Colours now come from the buyer; the logo rule stands. Every text pair keeps 4.5:1 contrast.
   Unthemed, --brand falls back to the ink (the old black-and-white look).
   Sizes in rem, so every box grows with the reader's text size. Type is fluid: clamp(rem, rem + vw, rem). */
