  // 2_02 赫默 医疗无人机 (AUTO, heal trigger): "获得一个医疗无人机 / 最多可库存1个无人机；无人机投入战场后治疗周围友军，
  // 10秒后自动销毁" — the 医疗探机 is a hand piece the player places (user playtest #6; PRTS 卫戍协议/帮助): each cast gives
  // one (stock ≤ cnt) and the placed piece takes the field on its own tile (tokens.js releaseSkillSummon: not at the
  // battle start — user playtest #4; not placed ⇒ no drone); it heals around itself and self-destructs after 10 s (token
  // kit). 强化注射: every 【医疗】 operator on the field ASPD +attack_speed. Elite module (PHY-Y): heals on ground units
  // ×heal_scale (module 'none': no bonus).
  // The cast: as soon as the SP is full — the AUTO skill has no cast condition (client skill skchr_silent_2: no
  // `_trigger`, `_allowNoTarget` 1, `_checkHasTargetBeforeDoCast` 0, a RechargeToken action), so the placed drone takes the
  // field the moment S2 is ready (community report of 2026-10-06 「赫默的无人机在2技能好了之后应该秒放」; until 0.2.0 the data's
  // DEFAULT rule with `heal` waited for an injured ally in her range). While the stock is full her SP stops (阻回) until
  // one is spent: `_stopSpWhenTokenIsFull` 1, PRTS 备注 「医疗探机库存达到上限后赫默获得阻回，直到库存被消耗为止」.
  // S1 治疗强化·γ型 (alt): ATK +atk for its duration (no drone).
