Planets, belts, wells, loot, mines, stations, the chunk reticle and the flow
clock are evaluated through DrawAhead (Time, Orbit, Height, Position) at one
drawn time; the rail law lives once in Zone.Offset; OrbitPositionAt, GetHeight,
ChunkPose, EvaluateBelt and RideHeight take a time. Fixes the planet jumping
against a co-moving ship at display rates above the step rate.

cloudDensity adds the R32 gravity height to the patch texture, so Main Menu and TestScene patch cameras (mask 5632) counted layer 9 twice. Mask 5120, and GravityFieldParityVerify now asserts each of ARPG, Main Menu and TestScene excludes layer 9 from its Fog Patch Displacement camera.
All commits build as far as C# goes; verify runs after the second commit.

Patch Displacement no longer culls layer 9; cloudDensity adds the surface displacement to the patch-only displacement.
GravityFieldParityVerify wiring checks the camera. Neither commit has been built when this is written.

core-at-roche-and-exaggeration-up: PlanetSettings.CoreRadius and Planet.CoreRadius are
deleted; the well's softened core reads the RocheLimit curve (one curve of mass). The
core < Roche guard cannot fail and is replaced by a Roche-limit-positive-and-finite
check. Settings.asset: CoreRadius removed, HeightExaggeration 10 -> 4.0983607
(10 / (7.32 / 3)). Tests pin the new curves and the peak drawn slope / 2.44x steeper tail.

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.

GravityShaderMirrorTests compares the expression of GravityField.Potential with gravityPotential in Gravity.cginc.
GravityFieldParityVerify now builds four off-axis bodies (one of mass 0), lowers through three frames with bodies moved
between them, and checks the map screen's gravity camera mask. RTS/Planet.prefab loses the Gravity Well object bound to
the Gravity Field material. Builds: yes (verify passes on Starfire; the new test is unrun until the Yggdrasil job).

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.
