Playtest #5 fixes: hovering enemies, target order, blocking hand-over, 联防 knocked-out, elements, huge-boss hit area, maps, gear icon, phone HUD, 至简 price

- #1 近地悬浮 enemies count as air units (Unit.isFlying): ground-only attacks, splash, terrain and traps skip them;
  PRTS 不可对空 skill effects made ground-only; 掠海漂移体 / 吉兆飞鳞 drop modes; the bot plans them as air
- #2 an operator knocked out before 联防 is fielded and force-exited (PRTS 强制退场): it lies on its tile with the
  redeploy ring and redeploys (full timer [ASSUMED]); partners, observers and the server fallback included
- #3 element audit of every operator, item and enemy: 海嗣 numbers are official; bursts are 无来源, 元素脆弱 only
  raises 元素伤害, 元素抗性 applied, 盟约·辅助干员 fills all three gauges, 菲莱 / 哈洛德 / 纯烬 / enemy kits fixed
- #4 blocking by the official contact radius (0.7071): another operator in contact takes over at once when the
  blocker dies, withdraws or is stunned; melee blockers attack what they block
- #5 enemy target order per PRTS 索敌: blocker, special priority, taunt, last deployed; initial deploy 从上到下>从左到右,
  operators before summons; special priorities break ties by taunt then deploy order
- #6 act2 m01's normal-field blower machines (row 13) are drawn in the normal / 联防 views
- #7 Final Assault prep legality reads the player's half of the boss field (fence tiles deployable); all 11 stages
  audited against the official level files
- #8 regular settings gear; #9 the prep camera keeps the bench and temp rows clear of the shop bar on phones
- #10 huge bosses have the official 4.95 × 2.95 hit area (sim/body.js) and are 自缚 / unblockable
- #11 至简 costs 1: 购买价格为N's bb.price is a discount off the tier price, applied before other price effects
- DESIGN §19 and the normative §3 / §5 / §6 / §7 lines, SIM / META / DATA / PLAYING updated; 2595 unit tests and
  every browser suite green; dev recordings regenerated
