/*
 * Catalog page styles (CATALOG-ENGINE.md §3). Catalog pages are rendered at
 * the edge from D1 (site/catalog/render.mjs) inside the Astro-built shell
 * (BaseLayout: tokens, header, footer disclosure), so they cannot use Astro's
 * scoped styles. These rules REPEAT the static book template's scoped rules
 * (site/src/pages/audiobook/[slug]/index.astro) and the calculator's
 * (site/src/components/Calculator.astro) under the .cbook prefix, so a
 * catalog page looks exactly like a static book page. Proposal §4.2 phase 3
 * moves both onto one shared core; until then a change to either template's
 * styles is mirrored here (qa-catalog.mjs checks the class inventory).
 * Book pages show the store cover from wave 1 (ruling 8, session 97,
 * supersedes C7): a smaller square box than the static 2:3 hero, lazy, never
 * the largest element (.ccover below).
