For songs with an `lrc` field in frontmatter:
- Verifies the file exists and is valid UTF-8 (warns and skips otherwise)
- Uploads to wiki as `File:<title>.lrc` via MediaWiki file API
- Idempotent: skips upload if SHA1 matches existing wiki file
- Appends `[[Media:<title>.lrc|Synced lyrics (.lrc)]]` before the
category tag at the bottom of the wiki page
Songs without `lrc` in frontmatter are unaffected.

render.py was a misleading name — the script validates, renders,
and writes to MediaWiki (and will soon upload LRC files too).
publish.py better describes the full scope of the entry point.
