unit_fx

Poses what the battle throws off, from the same unit table the bodies come from: the white-hot tracer leaving a firing trooper's muzzle and travelling up the canyon, the bloom at the barrel on the frame the round leaves, the cyan-green burst a Vesh comes apart in, and the ochre cloud a brute or a titan walks in. One mode per population, read from that population's cfg buffer, so a single shader and four buffers cover all four.

Only a share of rounds throw a visible streak, rationed by a hash over which shot it is: every trooper drawing one at once is a wall of light with no line under it.
