"""Canonical valid-value sets shared by the wizard and CLI flag validation.

The interactive ``_step_*`` functions in ``steps.py`` use these for ``Choice``
construction (or are checked against them by tests). The CLI ``onboard``
command in ``cli/commands.py`` uses them to validate ``--provider`` /
``--ui`` / ``--workspace-mode`` flag inputs.

Single source of truth — adding a new provider here AND to the corresponding
``Choice(value=...)`` in ``steps.py`` is required; a drift test in
``tests/test_onboard.py`` keeps both sides in sync.
