ovui-widgets application

Use a separate virtual environment for each configuration. Availability: as of this writing only the ovui core wheel is published on public PyPI; the ovui-widgets-* and ovui-data-adapters-* 0.2 distributions are not yet on the public index, and no complete public 0.2 wheel channel exists yet. The 0.2 release wheel set is attached to release pages on the access-restricted development repository (17 wheels; it has no standalone ovui-inspector distribution because the Inspector skill is embedded in each ovui application wheel); the public repository's releases currently carry only 0.1.x assets. If you have access to those wheels — a restricted release download, a CI wheelhouse artifact, or a wheelhouse built from source — add --find-links /path/to/wheels to the pip install commands below; the commands work verbatim against PyPI once the packages are published.
