"""User-story E2E tests for HearthNet — Playwright + screenshot proof.

Each test class is a complete user story. Every story:
  - uses a REAL two-node in-memory mesh (no mocks)
  - drives a real Chromium browser via Playwright
  - saves annotated screenshots to docs/screenshots/stories/

Stories covered:
  US-01  Alice asks a question → LLM answers (Ask tab)
  US-02  Alice queries with RAG context (Ask + corpus)
  US-03  Routing trace proves which node answered (Ask routing panel)
  US-04  Alice sends a direct message to Bob (Chat tab)
  US-05  Alice opens the Mesh tab → sees Bob (live SVG graph)
  US-06  Alice refreshes peer list → sees Bob's capabilities (Settings)
  US-07  Alice posts to marketplace → post appears in list (Marketplace tab)
  US-08  Alice ingests a document into the knowledge base (Settings RAG ingest)
  US-09  Emergency tab shows connectivity mode (Emergency tab)
  US-10  Bob asks a question — answer comes from Alice's LLM (remote routing)
  US-11  All 7 tabs are present with correct headings
  US-12  Join-mesh QR section is shown in Settings
