/**
 * check-studio-every-plugin — open EVERY plugin in the plugin studio and fail on any that is broken.
 *
 * USAGE:   bun run check:studio-all -- --url http://localhost:5299/            (dev server)
 *          bun run check:studio-all -- --url http://localhost:5478/index.html  (built tree, serve-strict)
 * Graded by EXIT CODE: 0 = every plugin mounted with content, 1 = at least one failed.
 *
 * ★ WHY THIS EXISTS WHEN smoke:studio ALREADY DOES. smoke:studio samples 4 tabs by index. On
 *   2026-09-25 a first-run sweep of all 35 found people-groups-grid rendering 2 DOM nodes and a page
 *   error — standalone, in the studio and inside two composites — and 13 plugins mounting with
 *   their data 404ing on a fresh clone. The sample had passed. A plugin the gift ships must be
 *   checked, not sampled; this takes ~2 minutes.
 *
 * WHAT FAILS A PLUGIN (each measured on a real defect, none guessed):
 *   - the studio's own error overlay ("Could not load …") — the element never registered
 *   - a page error while that plugin was active (the i18n crash above)
 *   - a failed request (4xx/5xx) while it was active — a data file that is missing is a plugin
 *     that looks empty. Mapbox tile/event hosts are excluded: a URL-restricted token 403s there
 *     and that is a deployment setting, not a plugin defect.
 *   - a mount with almost nothing in it (< 8 elements and < 50 characters): the blank grid was 2.
 *
 * --url is REQUIRED. Several gates here hardcode :5173, and a drifted dev server made them measure
 * another worktree's tree — so this one refuses to guess.
