Playwright writes a trace only when the trace option is enabled, and on-first-retry is the cheap setting

Traces are off by default. Set trace: 'on-first-retry' in the use block of playwright.config.ts so the first attempt runs at full speed and only a retried test pays the recording cost. A trace zip lands in the output directory beside the failing test and contains a DOM snapshot per action, the network log, console output, the source of each call and screenshots.
Open it with npx playwright show-trace path/to/trace.zip, or drop the file on trace.playwright.dev, which runs entirely in the browser and does not upload it. Because snapshots are captured before and after each action, a trace answers the question a screenshot cannot: whether the element was present and got covered, or was never rendered at all. trace: 'on' records every test and produces large artifacts, so keep that setting for local debugging.
