/* Studio websites (D-110, D-131 to D-134): one stylesheet, ten themes ([data-look]) and eight font pairs
   ([data-fonts]). The studio's colours come inline from the server, already made readable on the theme:
   --primary, --accent, --link (text links), --button and --on-button. Fonts are served from the site itself:
   nothing loads from elsewhere. Each theme's --paper, --soft and --ink are repeated in src/sites/design.rs,
   whose tests check them for contrast. */
