Lamp Layers - light one room in layers, with dimmer scenes

Place a room's lamps and the spots where people read, relax, work or eat on a to-scale plan; see the estimated light at each spot against its target, the ambient, task and accent layers, and dimmer scenes. A metered lighting plan writes one scene per spot and the lamps worth adding. Built on @curiositech/interior-design-expert (curiositech/some_claude_skills, MIT).
