Hand-built zones move from OrbitsFromFieldTests into ZoneWorlds so WellLawTests reuses them. Not yet run.

Gravity.cginc is GravityShader.Source() output. OrbitsFromFieldTests spell periods from GravityField.Pull composed as the law
(binary members feel the partner's pull at the chord, the outer body feels c(total mass)). Fixtures whose bodies carried
mass 0 under constant curves (WellFixture, the mining scenes) now carry a mass: the tree conserves mass. DrawnPoseTests'
rails use the Plummer pull. Builds; not yet run.

PeriodAround's ring term is one rule: self feels the mean, over the members whose pull it takes (itself if bodied, else every
bodied ring member), of half the rest of the ring. A station on a binary's ring no longer stands still. The 0.1 u window is a
named constant, pinned just inside and just outside it; a bodyless node's children are pinned never to read the node's parent's well.
Both commits build.
