Price weather

Median settled move in blended list price over the last 120 days, from ModelPriceWatch (CC-BY-4.0). Only models whose price changed are counted, so a flat catalog does not wash a real cut down to zero. Same-day flips in a series are not a settled move. When a lab figure comes from one model, the tile names that model. Cool fronts are cheaper. Warm fronts are dearer.
