+/**
+ * QA-1: App-weite E2E-Smoke-Suite (Playwright, getrennt von vitest).
+ *
+ * Zwei Betriebsarten:
+ *  - MOCK (Standard): startet den Vite-Dev-Server auf :5199 und fängt alle
+ *    API-Aufrufe per Route-Interception ab (Fixtures nach DATA-2-Vertrag,
+ *    siehe e2e/mock-api.ts). Kein Backend nötig.
+ *  - LIVE: `E2E_BASE_URL` zeigt auf das laufende Frontend (z. B. via Aspire
+ *    AppHost); es wird NICHT gemockt und kein Dev-Server gestartet.
+ *    Fixture-gebundene Tests überspringen sich dann selbst.
+ *
+ * Viewports: Smartphone (390px, mobile-first) und Laptop (1280px) — jede
+ * Spec läuft in beiden Projekten.
