Advanced tuning lab. This is the workbench with the full 25-slider rail and no explainer chrome. The public-facing Sundog page with the educational walkthrough lives at /sundog.
Parhelion Workbench

The Sundog Eye

A parametric exercise of the parhelion description. Tune the optics on the right; the static composition holds the still pose that the animation phases will narrate. The visual atlas renders the canonical halo geometry these sliders parameterize, the h-of-x page walks through the promoted parhelion-offset inverse equation, and the geometry shelf sits next to both as the routing surface for discrete-geometry discoveries.
