# One command, because the dashboard is the primary surface and it handles the
# rest: in a folder with no .vibestrate/ it opens an onboarding screen with
# Initialize project rather than a half-broken dashboard, and More > Setup
# walks the same checks `vibe doctor` runs. The old three-command sequence
# taught the CLI path to someone who had not seen the app yet.
