# Example: form regression check after a UI change You changed a mobile web form's CSS. Instead of trusting the desktop preview: ``` phone_look("is the submit button fully visible and not overlapping the keyboard?") phone_look("read back the values shown in the form fields") phone_tap(...) # submit phone_look("did the success toast appear? any layout shift?") ``` Pairs well with a git hook: after each deploy, run the same look-sequence and diff the answers.
