+"""独立校验交付的 .face（只看交付物 + 固件镜像，不看中间产物）。
+
+  rome: replace -> dist/S4PAnim.face        pay 应等于**改后镜像**的字节，fp 应等于**原厂**前 64 B
+        restore -> dist/S4PAnimRestore.face pay 应等于**原厂**字节，   fp 应等于**改后镜像**前 64 B
+  ① 从 .face 里抠出 Lua 表（pay / rb），按表里的偏移取字节
+  ② 每条 pay 长度必须 == 原厂槽位长度（等长覆盖的底线），且能按 LVGL RLE 解出 464x464
+  ③ rb 每条必须是 64 B 指纹，且等于另一侧字节的前 64 B（版本校验数据正确）
+  ④ 目标镜像的 inode 表 / superblock / 分区长度与原厂逐位一致
