+ * System Settings E2E Tests

+ * Tests the System Settings page functionality including:
+ * - Navigation and page load

+/**
+ * Break Glass Recovery - Restore Cerberus with Universal Bypass
+ *
+ * CRITICAL: This test MUST run AFTER emergency-reset.spec.ts (break glass test).
+ * Uses 'zzz-' prefix to ensure alphabetical ordering places it near the end.
+ *
+ * Purpose:
+ * - Break glass test disables Cerberus framework
+ * - Browser UI tests need Cerberus ON to test toggles/navigation
+ * - Setting admin_whitelist to test-runner ranges bypasses security checks for E2E
+ * - This allows UI tests to run with full security stack enabled but bypassed
+ *
+ * Execution Order:
+ * 1. Global setup → emergency reset (disables Cerberus)
+ * 2. Security enforcement tests (ACL, WAF, Rate Limit, etc.)
+ * 3. emergency-reset.spec.ts → Break glass test (validates emergency reset)
+ * 4. THIS TEST → Restore Cerberus + test-runner whitelist bypass
+ * 5. Browser tests → Run with Cerberus ON, ALL modules ON, but bypassed
+ *
+ * Why the test-runner whitelist is preferred:
+ * - Bypasses security for local/private test runners only
+ * - Keeps security enabled without opening global access
+ * - Still exercises the admin whitelist feature
+ * - Works in Docker, CI, and local environments
+ *
+ * @see /projects/Charon/docs/plans/e2e-test-triage-plan.md
+ * @see POST /api/v1/emergency/security-reset
+ * @see PATCH /api/v1/config (admin_whitelist)
