/* ==========================================================================
   Library — book cards + book details modal (2026-09-26)
   Loaded after page-library.bundle / unified-modal.css; every rule is scoped
   to #bookholder (library grid) or #bookModal so publications and other
   modals are untouched.

   Signature: books read as physical books on a shelf. Covers carry a spine
   shade on the inline-start edge (right on Arabic pages, where Arabic books
   are bound; left on English), and books without a cover image get a
   generated cloth-bound cover with the title stamped in gold.
