"""
scenes.py —— 区域(region) → 场景(scene) 归并表 + 每个场景的自然语言从句

归并依据是**实际画面**，不是区域名：
  · infiniteDungeonArenaA1 / F1 / LargeWaterfallA 是熔岩湖 + 焦骨桥
  · infiniteDungeonArenaC / D / I / P1 ... 是青光菌类的雾气地牢
    两者名字相邻，画面完全不同，按名字归并会把两个场景混成一个。
每个区域都抽了它自身亮度 p90 时刻的一帧目检（见 eybx/region_frames2/）。

prompt 模板（train/inference 必须逐字一致）：
    In a 2.5D top down view, {场景从句}, the player is {动作从句}.

18 条场景从句全部统一为 "in a ..." 开头。旧交付里能逐字恢复的只有 6 条，
其中 4 条原本是 on/at/over 开头（"on a high mountain pass" 等），为了统一一并改写；
其余 12 条本来就是重写的（旧机器上的映射表随代码一起丢失了）。

白模缺陷区整区排除：目检确认无贴图。willsFarmIrmgardHouseInterior 是这次新发现的
第三个（旧交付只排除了前两个），画面是白模 + 品红色缺失贴图块。
