Habitat Acoustic Privacy Planner — 2D Corridor Profile

This 2D companion to the 3D habitat acoustic planner drives the exact same verified physics — sound pressure spreading from a point source by the inverse-square law, and dropping by a fixed transmission-loss step at every partition it crosses — but renders it as a continuous, draggable top-down corridor with a live SPL-versus-distance graph running underneath. Instead of reading three snapshot numbers at the sleep pod's current position, you see the whole decibel curve along the corridor at once: the smooth spreading slope, the sharp step down at each bulkhead, and exactly where it crosses NASA's 50 dB sleep-quarters guidance. Drag the pod marker to relocate it, pan the corridor, and zoom in on any partition to see its step up close.
