Playwright (ad-hoc)

Not for app E2E. Those live in the consuming app's E2E test directories.

Run

1. Detect localhost: node lib/helpers.js from this skill dir, or ask for a URL.
2. Write a script to /tmp/playwright-test-*.js (never into the repo).
3. Visible browser unless the user asks for headless: chromium.launch({ headless: false }).
4. Execute: node run.js /tmp/playwright-test-*.js from this skill directory.

First time: npm run setup in this skill directory (installs Playwright + Chromium).
