Fetch manifest JSON to pin fixture names, sizes, hashes, and MIME expectations in automated tests.

Why does this format have a category-specific hub?

A category-specific hub keeps assumptions aligned with practical workflows and related format alternatives.

ICO 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.
