  // ---- 3_08 薄绿 · 阵法术师 — S2 聚能涡旋: each attack strikes every enemy on her range (the trait's 群体法术伤害) and
  //      pushes each one towards her, end-of-skill burst on
  //      every enemy in range; 地质学者: DEF aura (skill off) / less likely targeted (skill on);
  //      精锐 module PLX-X: keeps part of the guard (DEF/RES) while the skill runs
  //      S1 风语: wider range (skill grid), attacks every enemy on it at attack@atk_scale. Auto-cast: the official
  //      rule is the 阵法术师 row SEARCH (PRTS 卫戍协议/帮助 "不受基础策略影响，在初始攻击范围内存在敌人时释放技能"; it covers
  //      every MANUAL skill of the class — user playtest #6) = an enemy inside her INITIAL range, never any enemy on the
  //      field (she would burn the skill on enemies that just spawned). Since 0.2.0 the owner's ACTIVE_RANGE rule
  //      (2026-10-05) widens it: the S1 x-2 strictly contains her x-1, so the data rule is ACTIVE_RANGE on the x-2 (rawRule
  //      SEARCH) — an enemy she can target inside the x-2, every tick — which this spec reads. S2 keeps SEARCH (no range
  //      change).
