/**
 * Full-system real-browser multi-user acceptance (FS-*).
 *
 * Hard rules:
 * - Real Chromium clicks/fills only. No page.route mocks; no API create/project/message/approve.
 * - Multi BrowserContext (never share storageState across roles).
 * - Each page: console + pageerror → console-*.jsonl
 * - Unmet conditions → FAIL (or explicit SKIP with reason). Never fake PASS.
 * - PI / squad waits: 15–20 min timeouts.
 *
 * Gate: RUN_UI_ACCEPTANCE=1 + ADMIN_USERNAME/ADMIN_PASSWORD + BASE_URL.
