/**
 * E2E — Traffic Inspector page smoke tests
 *
 * These tests require the OmniRoute server to be running at the configured base URL.
 * The WebSocket tests use a mock event source rather than a live MITM capture to
 * avoid needing port 443 privileges.
 *
 * CI behaviour: marked `.skip` unless `RUN_TRAFFIC_INSPECTOR_E2E=1` is set.
 *
 * To run locally:
 *   RUN_TRAFFIC_INSPECTOR_E2E=1 npx playwright test tests/e2e/traffic-inspector.spec.ts
