A mobile trace renders inside the desktop browser chrome — mac traffic lights and an address bar showing unknown, since a native app has no url — with the phone as a narrow strip in the middle of a landscape frame.
Measured on a 1170x2532 capture: the image used 162 px of a 388 px frame; the remaining ~60% was backdrop.
Depends on the trace stating its device (see #345). With that available the player can shape the frame to the capture's own pixels and label it with the device instead of drawing window furniture that does not apply.
Fit by the decoded image rather than by the metadata viewport: the two disagree on both platforms — Android by the nav bar, iOS by compatibility scaling (an older binary on an iPhone 17 reports a 390x844 window while the screen is 402x874).
