/**
 * Stalker Portal E2E Tests
 *
 * These tests use the stalker-mock-server (apps/stalker-mock-server) to simulate
 * a real Stalker portal. The mock server starts automatically alongside the Angular
 * dev server when running e2e tests (see playwright.config.ts).
 *
 * Default scenario MAC (00:1A:79:00:00:01) provides:
 *   - 8 categories per content type (VOD / Series / ITV / Radio)
 *   - 40 items per category
 *   - 3 seasons × 8 episodes per series item
 *
 * Tag: @stalker — run only stalker tests with: nx e2e web-e2e --grep "@stalker"
 *
 * ISOLATION works on three levels, because one mock-server process is shared by
 * every spec file and its state is keyed by MAC:
 *
 * - ACROSS FILES: `beforeEach` resets only the MACs in `OWNED_MACS`, and the
 *   sibling files that touch this server (self-hosted, sources-pwa) own a
 *   disjoint `00:1A:79:5F:*` range, so neither can clear the other's state.
 * - WITHIN THIS FILE: tests deliberately share scenario MACs (`default`,
 *   `minimal`, `embedded-series` — their fixture shapes are what the
 *   assertions are written against), and every `beforeEach` resets all of
 *   them. Under the workspace-wide `fullyParallel` preset that would let one
 *   test wipe another's data or session mid-run, so each project/repeat group
 *   runs its tests serially in one worker.
 *
 * Giving each test its own MAC instead would mean inventing a scenario per
 * test; serializing one file is the cheaper trade.
 *
 * - ACROSS BROWSER PROJECTS/WORKERS: state-sensitive auth tests use one MAC
 *   range per Playwright parallel slot. Their `beforeEach` adds only that
 *   slot's MACs to the scoped reset, so concurrent projects cannot clear one
 *   another's token, invalidated session or pinned device id. A restarted
 *   worker retains its bounded `parallelIndex`.
