Markdown Style (GFM-first)

Mechanical formatting is handled automatically: every Write/Edit to a .md file triggers hooks/md-format.sh → prettier --write --prose-wrap preserve. That aligns table pipes, normalizes list markers (- for bullets, 1. ordered), code-fence style, and spacing. You write; the hook tidies.

Manual format (unformatted files, bulk):

prettier --write --prose-wrap preserve "docs/**/*.md"

Judgment calls (prettier can't decide these)
