The Nuxt version is being rewritten in Go. This is the design that came out
of it, split by how each part ages:
- CONTEXT.md glossary, English identifiers and Finnish UI wording
- docs/spec.md behaviour: rules, submission pipeline, routes, API contract, schema
- docs/decisions.md why, append-only
- docs/later.md deliberately not in v1
testdata/ytdlp-noose.json is a real yt-dlp dump used to test metadata
prefill against a video with no track, artist or album tags.
