 "title": "set_framerate() must be called before capture; omitting it silently pins the sensor to 60 fps and wastes 4\u00d7 performance at QVGA",
 "symptom": "Calling get_framerate() before set_framerate() raises 'Frame rate is not supported or is not set'; QVGA capture yields 60 fps instead of the expected 240 fps; sensor never runs faster than 60 fps at any resolution without the call",
