M4A Format Hub
M4A (.m4a) encapsulates AAC or ALAC audio within an MP4 container, adding support for chapter markers and metadata atoms. Common on Apple platforms, it’s ideal for music and podcasts. Use sample .m4a files to test container parsing, chapter navigation, and artwork extraction.

Implementation Notes
Use the manifest endpoint for deterministic fixture selection in CI, then validate MIME/type detection against actual parser output.
If this format appears in multiple categories, prefer category-specific hub pages to keep test assumptions aligned with real usage.
