|    -> Stored CONTIGUOUSLY (one cluster right after another) unless you  |
|       deleted individual photos mid-shoot and filled tiny gaps.         |
|    -> A carver scans for the TIFF/CR3 start header (49 49 2A 00 or      |
|       ftypcrx) and reads straight through to the end of the photo.      |
|                                                                         |
| 2. DUAL-STREAM VIDEO + PROXY + XML OR INTERLEAVED AUDIO/VIDEO (.MP4):   |
|    [4K Video Chunk 1][Proxy Sub-Stream Chunk 1][4K Video Chunk 2][Thumb]|
|    -> Many cameras record main 4K video (M4ROOT/CLIP/C0001.MP4) and     |
|       a low-res proxy (SUB/C0001S01.MP4) or XML telemetry simultaneously|
|    -> This interleaves clusters on disk: Main Video -> Proxy -> Main.   |
|    -> When formatting wipes the exFAT cluster chain, a naive carver     |
|       glues Proxy clusters into the middle of the 4K video file.        |
