about
nx_fluid_gate.nx -- ★R6: the height-field FLUID SIMULATION, proven by physics (not "pixels moved"):
T1 PROPAGATION: a drop's wavefront radius GROWS over steps (waves travel at finite speed; not static, not instant)
T2 ★CONSERVATION: total volume sum(h) is invariant across the sim (mass conservation = the correct-integrator test)
T3 REFLECTION + DAMPING: the wave reaches a far boundary (propagation across the domain) AND peak |h| decays
over long time (energy dissipates) -- and it stays BOUNDED (no blow-up = numerically stable)
T4 determinism + animation strip knowledge/nx_fluid.png (a drop rippling + reflecting across 5 frames)
