AFTERTONE layout adaptation of the credited Mutopia source.
Each numbered component retains its source license, including the adapted engraving.
See SOURCE.json in each component for author, license URL, source URL, SHA-256 and compatibility changes.
The upstream folder preserves the unmodified source; source/ contains the converted engraving input.
To regenerate: run the indicated LilyPond version on aftertone.ly in each component directory.
Changes concern syntax compatibility, printed layout and recorded diagnostic corrections; no new musical arrangement is claimed.
