Add CLAUDE.md Project instructions for Claude Code sessions, loaded automatically at the start of each one. It carries the writing rules that every page here already follows, and two things that are not visible from the pages themselves. A push is live with no review and no undo. And this repository's source tags cannot be used to establish history: they are dependency-bot artifacts and do not match their names, which nearly produced a confident and wrong correction to a page that was right.
