   templates/index.html, _book_cover.html, _cost_table.html (the cost table styles, formerly costs.css)
   and the share-image page _og_cover.html. Depends on the tokens in site.css. Mobile-first.
   Breakpoints: < 640px phone; 640-959px one centred column (max 560px); >= 960px desktop.
   Prefixes: .h- page, .bk book covers, .c- cost table.
   Blue (--c-brand*) is for actions only: buttons, links, focus rings, the "best value" row.
   Movement (transforms on hover, transitions, the progress animation) only under
   prefers-reduced-motion: no-preference; the static fan of the shelf is allowed everywhere.
