# VERTICAL SLICE - NOT FOR PRODUCTION

# 实现 GDD：design/ux/battle.md（§Transitions 结算逐行兑现——B 区因果演出链骨架：
|
||
# 结算轮光带自棋盘区横扫 → 伤害/治疗弹道自棋盘飞向敌我站桩 → 受击闪白与血条递减由站桩侧承接）。
|
||
# 位置语义：全屏覆盖层（A–D 区之上、模态之下），只做跨区飞行的演出载体——棋盘区内演出
|
||
# （清图金粒/完美排雷横幅/标中旗弹道/Boss 影子）仍归 board_fx_view。
|
||
# 高内聚边界：纯演出——组合根按结算信号调用 play_*，传全局坐标（组合根持有棋盘与站桩两域句柄）；
|
||
# 本类零核心依赖、不自持游戏状态、mouse_filter 全忽略（不劫持输入）。
|
||
# 动画密度/缓动曲线归战斗表现样张批终稿——本批落"因果全程可见"骨架（规划兑现 P2 义务）。

# Date: 2026-09-20（结算演出链批）
