+"""P45 evidence: crop the avatar cell from the real LV_P45_SHOT frames and upscale 4x.
+
+Reads the shot log for the character destination rect printed by the game
+(`dest=x,y,w,h`), crops that region (plus a small margin) from the full 1280x720
+screenshot and upscales exactly 4x with NEAREST. Pure function of real frames.
+
+Usage:
+    python3 scripts/make-p45-char-crop.py <record-dir> <shot-log> <out-dir>
