A burst fires for its whole window, and the countdown is the tile itself

The gun, beacon, flamer and rocket fell silent the moment they cleared the court:
firing and steering were both gated on phase 'rally', and every beat raised by the
kill that empties the court (a point, a won game, the mop-up) parks the phase in
'over'. A burst is its own control mode for its whole len, like a horde — its own
clock is the only thing that ends it. Not fixed by forcing the phase back to rally:
a parked 'over' beat that never expires is how pendingHorde gets stranded.

The countdown moved off the tile's bottom edge (the rounded frame, and the bottom of
the screen) into the tile: the armed slot's well drains as a gold wash, clipped to
its own rounded path, under the icon and labels.

16 tests.
