Debug — step through a replay

Click Debug (step through each event) to replay one step at a time. Trq pauses before each event; advance with Step over, jump ahead with Run to end, or Stop debug session. The toolbar shows paused at 4/12: click.

While debugging, the Inspector panel shows the element Trq is about to act on and its selector ladder, each rung graded:

stable (✓) — aria/…, text/…, data-testid/data-test/data-cy/data-qa, or a clean id.
brittle (⚠) — positional XPath or deep CSS.
dynamic (🚫) — framework-generated ids (mat-…, ng-…, :r3:, numeric suffixes) that change between loads.

Debug — step through a replay; the Inspector grades each selector stable, brittle, or dynamic

Use it to spot fragile selectors before they break.
