// Summon regressions from user playtest #2 (docs/DESIGN.md §14/§15; content/tokens.js, kits tier3 琳琅诗怀雅 / tier6
// 缪尔赛思, public/js/audio.js):
//   #4 琳琅诗怀雅's 香槟炸弹 is a summon, not an operator: using it up is no knock-out (no operator-knocked-down sound,
//      no death count, no "干员被击倒" effect); clients hear its explosion.
//   #5 缪尔赛思's 流形: never attacks before it copied an operator, the copy skill waits (ready) while nobody can be
//      copied, one respawn 25 s after being killed — never a quick second one (stale timers, her redeploy).
//   audit: official per-class death/deploy sounds for every summon kind (operator / summon / map character / device).
