// Documentation ⇄ code consistency (docs/DESIGN.md, DATA.md, META.md, SIM.md, README.md, DEPLOY.md, PLAYING.md).
// Every rule the final documentation sweep corrected is checked twice: the code still behaves as the docs now say, and
// the stale wording does not come back. Topics: combat / boss clocks in REAL seconds (overtime after 150 real s,
// m.public.overtimeAt), 联防 helper order (unite.helperOrder, research 08 §5), boss results handed over instead of a
// synthetic zero, reconnect windows (co-op 10 min, solo singleReconnectTime 24 h), g.equip replaceUid + equipped items
// locked, battleId unique per match, solo pause (g.pause / m.public.paused), road-over-floor lanes, module icons from
// local art, 标准 = 战场#01 only; user playtest #3 (DESIGN §17): temp overflow kept until the first prep its player can
// act in (never wiped at the round start), the 回环射手 boomerang and 蕾缪安's shells one by one, the live LP, the detail
// card order and the static game data; user playtest #4 (DESIGN §18): picking by the tile under the pointer and the
// dragged model held under it, a single human untimed, the strategy draft's one countdown, 机变 two taps, knocked-out
// operators and the official element gauges, live stats, the shop-only items, skill summons, 炎佑; user playtest #5
// (DESIGN §19): blocking by contact radius, 联防 forced exit, huge-boss hit areas and 自缚, the element pipeline rules,
// boss-field deployment, the phone prep camera — and the normative §3 / §5.1 / §5.5 / §6.1 / §7 lines that changed; user
// playtest #6 (DESIGN §20): summons placed by hand (start deploy), skill triggers and the operation cooldown, every
// blocker hits what it blocks, push force vs weight, the ASPD floor, the enemies' collider reach, the boss pool floor,
// multi-round bounties lasting two battles, the 联防 counter, the element gauge — and the user's settled decisions; the
// playtest6b follow-up (DESIGN §20.10–§20.13): leader HP and 直接乘算, the elite on the consumed copy's tile, the official
// 999 layer cap (one implementation) and 限伤 300000, the 假想敌：胄 kit — and the normative lines they rewrote; player
// feedback after 0.1.0 (DESIGN §21, v0.1.1) including batch 6 (§21.21–§21.25: 坚固维式重锤 once per deployment, 起飞,
// fenced tiles, knocked-out bodies, the dispatcher snapshot and the manifest shrink guard credited to PR #2 / PR #7) and
// the 突变细胞 bench rule (§21.1: the carrier destroyed, its new operator gained into the 整备区 — official footage, PR #2),
// the closing additions §21.26–§21.28 (GitHub issues #1 / #5 / #8) and the owner's deliberate trigger deviation for six
// 重装 skills (§21.29, GitHub issue #4 / PR #12).
