/* ════ 战斗动画 v0.5 —— 帧级还原 ═════════════════════════════
   素材：《赵云与阿斗》虎牢关实机录屏 30fps，dense/d_001–d_157 逐帧计测。
   原作实测参数（1 帧 = 33.3ms）：
   · 放置入场 d_028–031(r0c0)：1f 白底闪（格亮度 174→198）+ 2f 卡片淡入 ≈ 100ms
   · 字形战斗变形 d_080–098(r2c2 枪)：进入战斗后字形持续倾斜摆动，
     姿态角约 -63°↔-79°（摆幅 ≈16°），整周期 ≈6f ≈ 200ms
   · 命中反馈 d_069/d_078：整格压暗 1f + 黄色闪电符号 1–2f ≈ 66ms
   · 伤害数字 d_084–096：墨色数字带白晕，上浮 ≈1/4 格高，存活 3–5f ≈ 100–166ms
   · 死亡 d_035/056/088/091：1f 内消失 + 黑墨渍 1–2f + 白星闪 1f + 墨滴飞散 3–4f，
     总计 ≈4–5f ≈ 133–166ms
   · 移动 d_082→d_083：骑跨格 1 帧完成 —— 瞬移，无滑动补间
   · 近战武器 d_084–092：白色小刀图标在攻击者侧挥动，逐帧变角，存活 2–3f
   · 远程箭矢：小黑镖 1–2f 飞抵目标                                        */
