# VERTICAL SLICE - NOT FOR PRODUCTION
# 实现 GDD：design/ux/battle.md（D 区 AP 条 44px——点阵+数字〔pattern 5 点阵资源显示〕、
# 停手按钮居左、图例+弃图刷新按钮居右〔雷图右上角〕；弃图刷新确认微交互与常规确认不同位
# 〔pattern 7 破坏性确认异位：RAP 扣费 · 旧板旗作废显式代价〕）。
# 2026-09-26 信息归属批：RAP 读数（点阵+数字）自 C 区迁入本条、置弃图刷新按钮左邻
# （RAP 唯一消费口 = 弃图刷新——就近原则；RAP 清零反馈/资源拒绝脉冲载体随迁）。
# Date: 2026-09-12
# 高内聚边界：纯视图——意图经信号外发（stop_pressed/refresh_confirmed/legend_toggled），
# 状态由组合根经 setter 注入；刷新可用性预判 = RAP≥8 读数（行动经济 无推送信号——每次调用返回后重查）。
