✨ HR Diagram

What the encoder learned, on the Hertzsprung–Russell diagram. Point colour = one of 10 unsupervised K-means clusters of the 128-d embedding; point shape = the catalog family (tap chips to isolate). The encoder's input was the light curve only — never colour, never distance — yet its clusters land on the instability strip, the giant branch, and the eclipsing-binary main sequence (cluster↔label ARI = ). White-ringed stars are the poster's light-curve-zoo examples. Grey background: all good-parallax Gaia sources.
