 ### G5 — Impact ladder (hit-stop canon mapped to our camera-only stack)
 `Time.timeScale` stays banned (netcode); our hit-stop = camera `Hold` + FOV kick + flash — same ladder, per R5:
 - **Scale with significance:** chip hit = flash only; solid melee hit = 2-frame hold (current) + directional

 ### G7 — Responsiveness contract (buffers + cancels, netcode-shaped)

   a lock fires on the first legal tick (R7 buffer method; our `InputEvent`s already latch per tick — the buffer is
