// 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.
