  // 1_08 德克萨斯 剑雨: +cost DP; every enemy around (skill grid) takes two hits of atk_scale × ATK arts and is
  // stunned `stun` s — air units too (PRTS 备注 "※可对空"). 战术快递: +cost initial DP. (Elite hidden runtime_cost −4
  // "首次部署时部署费用-4": the initial deployment is free in battle ⇒ no effect.)
  // Alternate S1 冲锋号令·γ型 (AUTO, no target): +cost DP at once. An AUTO skill keeps its normal rule in this mode
  // (research 03 §1.4: only MANUAL skills are converted by the trigger table) ⇒ it fires as soon as SP is full.
