// Separate config from vitest.config.ts's jsdom project, for the tests that
// need a real browser (*.browser.test.ts) — real Chromium instead of jsdom.
// Two kinds qualify: layout regression tests, where container
// queries/clamp()/the flip-card's 3D transform actually compute the way a
// real window would, and the persistent artwork store, which jsdom has no
// IndexedDB for at all (a stand-in would only test the stand-in). These are
// slower (a real browser launches per run) and few in number, so they're
// kept out of the default `pnpm test:unit` loop — see package.json's
// `test:layout`.
