One-screen 640x360 arena (walls, grid floor, fixed view), mech with positioning-only movement (WASD/arrows, accel/decel, no aim), auto-fire KINETIC hardpoint (nearest-target, visible range ring) firing slugs that damage + knock back, untagged grunt trickle spawner with contact damage, hull bar HUD, scene-reload on hull zero. Headless smoke gate: tests/smoke.tscn asserts boot, piloting movement, spawning, input-free auto-fire, grunt lethality, knockback displacement. 3/3 passes on nh3-dev headless 4.7.1.

## Untagged grunt — the Act-1 learning-language enemy. Walks at the
|
|
## mech, deals contact damage on a tick. Untagged = neutral hue, no
|
|
## tag behavior. Knockback state lives here so KINETIC (and later
|
|
## chemistry) has something to shove.
