On the Android Automotive 15 emulator, screencap wrote "FORTIFY: pthread_mutex_lock called on a destroyed mutex" after the PNG's IEND in 38 of 39 trace screenshots, and in mobium screenshot. Image viewers ignore it; ffmpeg reported every one as damaged. A capture is now cut at IEND when a short line of text follows, the rule CHALLENGES 211 applies to text before it; anything else after it is refused. A car screenshot then ended at IEND. make ci passes.

On the Android Automotive 15 emulator 38 of 39 captures in a trace ended in a FORTIFY warning after IEND, and so did mobium screenshot. Cut, the capture ends at IEND.
