/**
 * Mobile catalogue (auron-theme/mobile-catalogue).
 *
 * Lives inside the mobile menu overlay, which is dark in both colour schemes;
 * the --auron-menu-* tokens come from that overlay (block-styles.css, "Mobile
 * menu") and the fallbacks here are the same values, for the editor preview.
 *
 * Two states:
 *   - no `.is-ready` (no JavaScript): metals stacked under headings, every
 *     row a link, every panel open beneath its row;
 *   - `.is-ready`: one metal behind the tabs, rows drill into their panel.
