Phase 8: bomb juice — the explosion is finally FELT

- Camera shake (G.shake, decays over 0.35s; HUD stays steady via transform reset)
- One white flash frame (G.boomFlash overlay)
- Scorch crater: near-black stain the boys mop 10x slower — the lawn scars
- Hitstop 0.1 -> 0.18
- Umpire loses composure: 'Order. Order, please.' (new order.m4a), rate-limited
  so bomb chains don't spam him

Verified: explode kills cluster of 4 (MASSACRE x4 chains), shake/flash set and
decay clean, 2nd bomb order-call suppressed, 1s of mopping erases blood (0.9->0)
but not the crater (1->0.84); screenshot mid-shake; no console errors.
