PNG sizes may be device-pixel scaled; on a Retina display the 1280x800 logical viewport
is usually saved as 2560x1600.
Run `npm run test:e2e:browser-throttling --workspace=@getpaseo/desktop` to verify
that hiding the window stops guest animation, viewport screenshots contain fresh
pixels, and restoring or closing the browser still works. Pass `-- --full-page` to
also run the below-viewport pixel assertion: this reproduces the existing
[full-page repetition bug](https://github.com/getpaseo/paseo/issues/3196), which the
capture harness's frame-availability checks do not detect.
On Linux, run it under `xvfb-run -a` when no display is available.
The existing `npm run test:e2e:browser-tabs --workspace=@getpaseo/desktop` journey
verifies that a hidden window stops guest animation, captures fresh viewport pixels,
and resumes animation after restoring the window. Its artifacts include the screenshot
and animation measurements. Full-page content correctness remains separately tracked in
[the full-page repetition bug](https://github.com/getpaseo/paseo/issues/3196).
