- playwright.config.ts: desktop (1440) + mobile (Pixel 5) projects, static
webServer over the exported out/; a PW_CHROME env override for the browser
- tests/e2e: render + all core sections, tracked download hrefs with no R2
exposure, the live counter (mocked function), theme toggle, image loading,
zero console errors, and responsive nav (desktop links / mobile menu reveal)
- navbar: hide the closed mobile menu with `invisible` so its links stay out of
the tab order and the accessibility tree, not merely clipped
- add the test:e2e script and ignore test-results/ + playwright-report/
