/* ============ SCANNING / LOADING SCREEN ============
 * Full-screen overlay served by scan-result.php (markup in
 * partials/scan-loader.php) while a scan is queued or underway. It polls the
 * backend and reloads the page once the scan resolves.
 *
 * One state on screen at a time — no step list. Every visual keys off the
 * [data-state] attribute on .scan-loader:
 *   "pending" — Completed = 0, waiting for a worker  → amber accents
 *   "running" — Completed = 2, scan underway         → pink accents (default)
 *   "done"    — parting frame set by JS just before the reload → green
 * Relies on the theme tokens defined in css/styles.css. */
