// Community report of 2026-10-06 「Touch策略给的医疗干员会跟炎盟约的炎祐冲突，无法同时出场」 (item 23): the 炎 bond's 炎佑 and the
// 外勤医疗 map character spawn at the same battle start; the 炎佑's free-tile search (tokens.js airTile: void tiles nearest the
// half's centre) took the medic's stage slot (data/stages.json mapChars, (10, 2)) on 战场#08 涨潮控制 (and 战场#07 with two
// 炎佑), so the medic found its tile taken and never stood. The map characters' positions are held for them now.
