Module download_assets 

cargo xtask download-assets — download static assets from the Plato release.

The Cadmus distribution requires several directories of static assets (bin/, resources/, hyphenation-patterns/) that are not stored in the repository and are not included in the Cadmus release artifact.

Temporary workaround

These assets are sourced from the upstream Plato release zip until issue #64 is resolved. Once Cadmus builds these directories from source as part of cargo xtask build-kobo, this entire task becomes unnecessary and should be removed along with the CI step that calls it.

Caching

Extracted asset directories are cached under .cache/plato-assets/<version>/ so that CI can restore them with a version-keyed cache and avoid re-downloading the zip on every run. The workspace-level directories (bin/, resources/, hyphenation-patterns/) are populated by copying from the cache directory.
