Teaching Board

Front-of-class board spanning a full 3m teaching bay and mounted flat to the wall at 0.9m sill, with a surface knob from a green roller chalkboard in a timber frame with a chalk tray to a white dry-wipe panel to a lit flat interactive panel with a slim bezel.

风格：low-poly, flat-shaded vertex colors, no textures, single shared material, so any set of these merges to one draw call; shares palette and scale with its kit
