ControlsFour phase buttons (Molecular cloud / Cold neutral / Warm neutral-ionized / Hot ionized) isolate a phase, dim the others and pan the camera to it, updating temperature/density/pressure stat boxes; clicking the active button again deselects it; Reset view button restores the overview camera and clears the selection; drag to orbit, scroll/pinch to zoom.
