RES 0.3.1

• REPORT.html redesigned for reading: a header with the product and study status, a notice that the page is for people and that AI agents should read BUILD.md (also as a comment at the top of the source), numbered sections in reading order (overview, product, screens, flows, rules, data, API, design, build plan, then what to prepare before launch), a coverage bar, rules and barriers as cards, IDs as badges.
