A camera framing change splits the timelapse geometry mid-run

Mirror/flip/rotate/digital zoom are baked into the stored frame (2026-09-12 pass), which is right: the frame on disk is the record the timelapse and the coming plant regions read. The consequence is that changing the framing re-frames the record from that moment on – frames either side of the change differ in geometry and a timelapse spanning it jumps. Today the drawer only says so. A later pass could stamp a framing epoch per frame or day folder and have assemble_timelapse either refuse a mixed range with a clear reason or normalise by letterboxing to a common frame. Also relevant to S7 plant regions, which are pixel regions in a fixed frame.
