about
nx_gassim_gate.nx -- NATIVE verify of the browser kinetic-theory gas sim (base = mmap; SAME code runs in the
sovereign WASM). Proves real statistical-mechanics physics: (1) the gas runs and collides, (2) every particle
stays contained (no tunnel/escape), (3) total kinetic energy is conserved over a long run (elastic dynamics),
(4) an isolated head-on elastic collision conserves total momentum AND kinetic energy EXACTLY, (5) THERMALIZATION
-- starting from a single speed the velocity distribution spreads (onset of Maxwell-Boltzmann), (6) raster -> PNG.
