🌡️ Ballistic vs Diffusive Phonon Transport (2D)

Canvas2D companion: phonons cross a nanoscale channel, flying straight (ballistic) when the channel is thinner than their mean free path and random-walking (diffusive) when it isn't, with a live Knudsen number and effective thermal conductivity readout.
