Mobile QA checklist

Mobile walkthrough checklist before launch: home, start, recommender, product, checkout, trust, result, account.

Before release, the site is checked not in theory, but with a thumb on a real phone.

Mobile rule: If a path cannot be completed on mobile in a few calm steps, it is not ready.
