# Until now nothing ran the test suite on a change: the release workflows
# build the app, web-check.yml type-checks the wasm target, and pull requests
# reported their own local runs. Run the workspace tests on every push to
# main and on every pull request. There is deliberately no formatter check:
# the tree is not rustfmt-clean and is not going to be reformatted.
