/*
 * Tarot Arabi — P10 books
 *
 * The book library and the single book product.
 *
 * This is a composition layer, not a new design language: tokens, buttons,
 * badges, breadcrumbs and icons all come from the global layers, and the library
 * hero mirrors the approved Page-family hero geometry so the book section is
 * unmistakably part of the same site. What is its own is the book object — a
 * portrait cover stage that never crops real artwork, a library grid that is
 * deliberately quieter than the course grid, and a cover-first product hero.
 *
 * Loaded only on book surfaces: the homepage, the Learn family, the card library,
 * the spread family and the course family each keep their own system, and none of
 * them receives these rules.
 *
 * There is no book script. The reveal gate the other families use is scoped to a
 * class their own script adds, and the global `ta-js` marker is already present on
 * every request — hiding book content behind it without an observer to reveal it
 * would leave the page invisible. Book pages therefore ship no motion and no
 * script, and every book is visible immediately.
