OpenJPEG is a non-default workspace member so release tooling can package the
adapter explicitly, and imaging reaches it only through the optional
dependency. Skia is likewise an optional, target-specific dependency. The
dependency. The independent `rust-j2k` feature reaches only the audited
pure-Rust `j2k` graph; enabling both features keeps both explicit codec types
available for interoperability testing. Skia is likewise an optional,
target-specific dependency. The
consolidated required Gitea gate exercises both optional features on
`ubuntu-latest` while its minimal-feature check proves that no native codec is
needed for the owned Rust and translated compatibility tests.
