The laws are Playwright tests in tests/. They open the page by its file address in headless
Chromium, one at a time:
npm install
npx playwright install chromium
npm test
Mouse capture in the tests is always a stub (a real requestPointerLock in headless Chromium on
Windows can clip the user's cursor).
