# VERTICAL SLICE - NOT FOR PRODUCTION
# 棋盘渲染帧取证探针（2026-10-01——数字墨族按板自适应修复的目视验证面：机检≠看得清）。
# 必须**窗口化**运行（headless 无渲染面）：
#   Godot_console.exe --path . res://smoke/board_shot_probe.tscn -- <输出目录>
# 流程：L1/L2/L3 各起一板（真实 LevelRunner+settle_batch 驱动 ~18 步 novice——自然揭示数字/旗），
# BoardView 真渲染，frame_post_draw 同步后抓视口 PNG。零存档触碰（无 save_manager 引用）。
