- P40ArtTests 6 例：连贯带覆盖路网且抑制孤立散布、摆放确定性、红灯笼落门口、
  红/石灯笼同光晕路径、同 seed 重生成一致、P40 索引在界内
- AssetPackTests 索引列表加 19/20；fsproj 注册 P40ArtTests
- scripts/make-p40-closeups.py 乌篷船 2x NEAREST 特写
- docs/维护说明.md 追加 P40 小节；证据 4 帧白块检查 0 命中，重复运行 byte-identical
- Release 全量 Desktop 201/201、Kernel 119/119 exit 0

+"""P40 evidence: NEAREST 1x->2x close-up of the Wu Peng boat at a doorway cluster.
+
+Takes the real 1280x720 game frames captured by the `LV_P40_SHOT=1` hook and
+crops the boat region, upscaling exactly 2x with NEAREST so pixel edges stay
+sharp (no mixed colours). Deterministic: fixed crop box, pure function of the
+input PNG, so running twice yields byte-identical output.
+
+Usage:
+    python3 scripts/make-p40-closeups.py <record-dir> <out-dir>
