"""P43 evidence: NEAREST 2x close-up sheet of the two new HUD cards.

Crops the top-right calendar/clock card and the bottom 10-slot hotbar from the
`LV_P43_SHOT=1` day frame and stacks them at exactly 2x with NEAREST so pixel
edges stay sharp.  The sheet is a pure function of the input PNG (fixed crop
boxes, fixed gap), no synthetic pixels.

Usage:
    python3 scripts/make-p43-hud-closeup.py <record-dir> <out-dir>
