r"""shot_checker.py — 整屏截图 B 档断言骨架（迭代 9 卡⑰a 2026-09-30）。
|
||
|
||
用法: python tools/shot_checker.py <截图目录> [shot_menu.png shot_camp.png shot_level.png shot_battle.png]
|
||
断言（v1 骨架——像素级可判层）:
|
||
① 四屏 PNG 存在且尺寸 = 1280×800（工程逻辑分辨率档）;
|
||
② 每屏灰度标准差 ≥ 8（非空白/非纯色——渲染真实发生的最低证据）;
|
||
③ 每屏唯一色数 ≥ 64（内容丰富度下限——占位纯色屏会落在个位数）。
|
||
T8 整屏样张闸四断言（全局文字 ≥4.5:1/明度三档带/焦点预算/文字禁压纹理）在本骨架上扩。
|
||
退出码: 0 = 全过 / 1 = 有失败。
