"""DELETE /fonts/<name> must refuse every font the repository ships.

The api's SYSTEM_FONTS was a hand-written list that had drifted from
backup_manager.BUNDLED_FONTS: MatrixChunky8X, MatrixLight6X, MatrixLight8X and
ic8x8u were missing, so deleting them removed git-tracked files (and the next
`git pull` either restored them or conflicted).
