Run goldens rebaseline

Blessing a golden overwrites the only record of what the UI used to look like. It is the one operation in the test suite that destroys an assertion instead of running it, so it is a manual, low-freedom, human-run workflow: execute the steps in order, do not improvise, and never run it to make a failure go away.

The two-lane golden strategy, the harness, and why goldens are the weakest visual assertion belong to widget-golden-and-a11y-testing. This skill is only the ritual for changing the baselines.
