createDominoChain: a run of real dynamic slabs standing in a row. Roll into
the first and physics topples the rest; when the LAST tile (red-striped so the
payoff end reads) tips past 45 degrees the chain emits its `emits` signal
exactly once. A domino run is a Rube-Goldberg wire: knock it here, something
fires over there. Passive physics like the see-saw, so no telegraph — the
visible topple IS the telegraph. race:respawn stands every tile back up.
Placed in Toaster Alley on the right shoulder: detour into the row and the
completed chain triggers a signal-only GREEN cannon volley (interval 0 = never
auto-fires) that paints you from across the course — a third, silliest way to
earn the gate's green (~10%, a top-up; mine and bubbles stay the main routes).
Verified deterministically with world.tick() (no more wall-clock waits in the
throttled tab): blob knocks tile 1 -> all 8 topple -> signal emitted once ->
both cannons hit (2 green splats, 9.9%) -> respawn re-arms all 8 upright.
tsc + build green.
