assertVisible

Assert an element is visible by its snapshot ref (e.g. y778 from [y778] “Network & internet”). Checks the current snapshot only; it does not wait for an element to appear. The element’s text is checked too, so assert the element that shows the value you are verifying, and not one whose text changes from run to run (a timestamp, an order number): replay would fail on it, so assert a stable label beside it instead.
