   books-public.css — the public /books page (resources/views/books/*).

   Ported 1:1 from the approved books.html mockup. Header, breadcrumb,
   footer, dock, toast and the design tokens (--primary, --radius-*, ...)
   come from public-shell.css, so only what is specific to this page lives
   here. Card classes (book-box-card, book-cover-wrap, ...) are deliberately
   the same names the homepage "Books by Our Trainers" strip uses.
