 For visual changes, such as omarchy-shell styling, desktop appearance, screenshots, or screen recording flows, verify with the running UI in addition to automated tests. Take and analyze screenshots with `omarchy capture screenshot fullscreen save`. For animation, transitions, capture, or screen recording behavior, make a short recording with `omarchy screenrecord --fullscreen`, stop it with `omarchy screenrecord --stop-recording`, and review the output before finishing.
