🧪 Classroom Inclusive Classroom Simulation

Design an accessible classroom by placing students with different needs — low vision, hard of hearing, wheelchair users — around a real 3D room and watch a live accessibility score for every seat. Sound level follows the inverse-square law with an off-axis directivity penalty, visual quality follows the angular size the board subtends from each seat, and mobility scoring rewards aisle-adjacent seats and roomy row spacing. Reshape the room with the row count, row spacing, aisle width and ambient noise controls to see how a few centimetres of extra aisle or a closer front row can turn a failing seat into a good one.
