What a site needs on a phone and in Google, before you publish

A new page in the documentation, A site that works on a phone and in Google, lists what most sites miss: the viewport line, buttons large enough for a finger, photos with their size and an alt text, one title and heading per page, and business details that Google can read. The AGENTS.md from the portal now gives the same points to the AI tool that builds your site, so it gets them right from the start.
