// test/content/feedback5-wv-summon-triggers.test.js — 0.2.0 WV #2: the owner's larger-range rule through summons (the
// owner's decision of 2026-10-06: "a skill whose effect reaches farther than the operator's own range casts when an enemy is
// inside the larger area"). A skill that acts through its owner's summons casts on an enemy inside such an area of a summon
// standing on the field, on top of its data rule (DEFAULT: an enemy in the owner's own range) — kits/shared/summoner.js
// summonTriggerArea (a content trigger range, server/sim/skills.js addTriggerRange with a `{ keys, profile }` entry):
//   * 麦哲伦 S1 高效制冷模块 — her drones' ranges (air units too: its 停顿 / 束缚 reach them);
//   * 令 S3 宁作吾 — each summon's x-5 (ground enemies only: its pulses "不可对空");
//   * 电弧 S2 环形鳞地 — 赛柯's range (ground only: its bullets reach no air unit); S3 手牵手 — 桑特拉's range (air too).
// Run: node --test test/content/feedback5-wv-summon-triggers.test.js
