Docstrings, comments, documents, guides, and the changelog are written in
ASD-STE100 Simplified Technical English, with Canadian spelling.
docs/development/writing-style.md has the rules, the six rules that we
bend, the conventions for docstrings and comments, and the glossary: one
word for each concept, an extension of the lexicon in CLAUDE.md. CLAUDE.md
now points to it and says which texts are not in STE. The release skill
writes the changelog in STE, under headings in the Keep a Changelog form.
