Preflight failed on skills/media-use/audio/references/tts.md — the section I added
was not oxfmt-clean. Formatted, and regenerated skills-manifest.json since the
media-use hash changed.
The other files oxfmt flags (package.json files, several skill .md files,
studio/parsers sources) are not touched by this branch and fail on main too — a
pre-existing whole-repo format debt, not introduced here.
