+"""P43 HUD analysis: prove the new calendar card + energy bar + hotbar are real.
+
+Reads the `LV_P43_SHOT=1` frames and the shot log (which prints the layout rects
+computed by HudLayout in the running game), then writes
+docs/evidence/p43-analysis.txt with the measured numbers:
+
+  1. calendar card / hotbar / slot0 rectangles exactly as the game laid them out,
+     all inside the 1280x720 viewport and non-overlapping;
+  2. per-slot hotbar brightness (10 distinct cells) and the selected-slot delta;
+  3. calendar-card and hotbar opacity is semi-transparent (never an opaque block).

+Usage:
+    python3 scripts/analyze-p43-hud.py <record-dir> <shot-log> <out-txt>
+
+Exit 0 when checks pass, 1 when they fail, 2 on usage/read error.
