One zone node at the massive roots' centre of mass owns the only global term (SubzoneReach is the one place the subzone shape is decided: isolated-subzones). WellNode gains Extent and Anchor; a belt orbit's extent is its outermost asteroid. GravityField.SeriesFrom = 0.4 is emitted into the shader template and Gravity.cginc. Tests: the spec's WellLawTests; the old seam test is replaced by TheBandPotentialIsExactInSinglePrecision. GravityFieldParityVerify runs the multi-root fixture (second sun, moon inside the planet's Roche limit, far window): PASS, largest drawn tau 1.228, max error 0.01028 u. The dotnet suite has not been run at this commit.

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.

The mirror test compared a normalised reading of two spellings and was beaten twice (a statement before the return, gravityHeight's sum). GravityShader writes the whole file (potential, zero-strength guard, reference term, height sum) from GravityField's constant (TailOffset); GravityShaderTests fails on any difference. GravityShaderMirrorTests deleted. GravityFieldParityVerify opens Main Menu.unity: no ZoneRenderer there, its Fog Surface Displacement camera is the menu's own brush presentation (layers 9 and 10) by spec.
Builds not yet verified on this commit; verified at the final merge.

Zone.WellReference owns each body's reference zero (GetHeight uses it). Gravity.cginc mirrors GravityField.Potential;
Brushes/Gravity Field draws depth = -h on layer 9 from a StructuredBuffer that GravityLowering.Lower fills from the
zone each frame; GravityLowering.CreateField makes the one quad. GravityFieldParityVerify renders it and compares every
texel with -Zone.GetHeight (max error 0.0059 u), the gradient with GetForce (0.03 degrees) and the wiring.
Deleted: the Gravity Well children of Planet, Gas Giant, Sun and PlanetOutpost prefabs, Wormhole 1's three gravity
children, their overrides in Main Menu and TestScene, five wormhole/wave materials and two brush shaders,
Planet.GravityWellDepth/Radius, BodyData keys 6-7, PlanetSettings.GravityDepth/GravityRadius (and the Settings.asset
keys). Surface Displacement culls layer 9 only. Headless build and tests not yet run at this commit.
