AGENTS.md

+**Run tests headless** (no browser window): Set `HEADLESS=true` when running e2e tests unless you need visual browser debugging:
+
+```bash
+HEADLESS=true pnpm test-dev-turbo test/path/to/test.ts


headless is the default. Doesn't need these.

timneutkens

Looks good except that one change.

timneutkens

I've pushed up a fix for the comment.
