/*
 * /books/shell.css — customer-side default styles for the mirror shell.
 *
 * Brick 1 minimum-viable defaults so the mirror looks presentable at first
 * deploy. Brick 4 turns this file into a customer-editable surface — you can
 * replace it entirely or tweak any rule below from the customer admin.
 *
 * Targets the class names emitted by johndelavera's hub.php fragment:
 *   .book-grid       outer wrapper
 *   .book-card       each book
 *   .cover           background-image-based cover
 *   .cover-empty     fallback when no cover image
 *   .cover-empty-title
 *   .info            text block under cover
 *   .title           book title
 *   .genre           book genre
 *   .badge           status pill (with .badge-live / .badge-soon / .badge-hidden)
 *
 * Class names are part of the public mirror contract (see STATUS doc §4 item
 * about Level-2 semantic CSS) — they will not change without notice.
