/* 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). A neutral palette: never the buyer's logo or colours ("<Buyer> branding applied on award").
   A demo may change ONLY --accent / --accent-ink / --accent-soft (both themes), and must keep 4.5:1 contrast.
   Sizes in rem, so every box grows with the reader's text size. Type is fluid: clamp(rem, rem + vw, rem). */
