name: Format

# Repo-local dev gate: enforces Prettier formatting on every Prettier-supported
# file. Distinct from lint-markdown.yml (markdownlint, reusable for consumers) —
# Prettier is this repo's own formatter (a committed dev dependency, see
# package.json), NOT part of the published standard, so this workflow is not
# reusable and installs from the committed lockfile. Prettier honors .gitignore,
# so .venv/ and caches are skipped without extra config.
