How we checked
We loaded the home page in Chromium as a 390px phone and a 1366px desktop, found the main button by its words (sign up, book a demo, get started and similar), tapped it once, and checked up to 3 pages for broken links and dead taps. Nothing was submitted. Each failed check costs the points shown. Full method.
