 * Scoped to .ra-books-archive.
 * Design tokens and utility classes mirror events-archive.css exactly.
 *
 * Design extracted from the Lovable Books Archive (src/routes/books/index.tsx
 * and src/components/site/cards.tsx) and translated to the ReachAbel WordPress
 * CSS architecture:
 *
 *   - Centred editorial card layout (text-center, no border)
 *   - Book cover on warm sand background with deep drop-shadow
 *   - zoom-frame hover on cover
 *   - Format badge in small-caps above the display-serif title
 *   - Signed badge in gold
 *   - Subtitle in ink-soft below title
 *   - Gold price
 *   - Trust strip: sand background, 3-column, icon + display heading + body
