/* Public store pages (/store and /store/<slug>).
 *
 * Built on the same layers as /mqllock: theme-dark.css, auth.css (buttons,
 * aurora backdrop, --auth-* tokens), contact.css (contact cards) and
 * mql-lock-page.css (container, sections, cards, steps, plans, FAQ, videos,
 * dialog and the scroll reveal). This file adds only what the store needs:
 * product cards, badges, the product hero, the screenshot gallery and
 * viewer, the description prose and the details table.
 *
 * Motion follows the /mqllock rules: only transform and opacity animate,
 * sizes are reserved up front (no layout shift), hidden start states apply
 * only after store-page.js has put `mql-reveal` on <html>, and under
 * prefers-reduced-motion nothing moves. The hero (icon, h1, short
 * description) is never animated.
