These tests exercise features that need a real HTTP server (workers, sockets, eventsource) and can't run in the normal Playwright test suite.

Workers need the library served at a URL (for importScripts).

# from the project root
npx serve .
# then open http://localhost:3000/test/manual/workers.html

These need live WebSocket and SSE endpoints.

# requires the `ws` package: npm install ws
node test/manual/server.js
# then open http://localhost:3000/test/manual/connections.html

The server provides:

• GET /sse - SSE stream: one message event, five tick events (JSON), one done event
• GET /sse-named - SSE stream: greeting and farewell events (JSON)
• WS /ws - WebSocket: echo + RPC (add, greet, failPlease)

Both pages run tests automatically and show pass/fail results.
