Room predictions that go beyond a compass

The extension doesn't just tell you which direction a home faces. It figures out what that means for each room - living room, kitchen, bedroom, home office - based on typical floor plans and the building's orientation.

What the grade knows: address, building direction, latitude, and seasonal sun path. What it cannot see: curtains, interior paint, every nearby obstruction, or an unusual floor plan. Treat it as a better tour filter, not an indoor light meter.
