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. Not yet built or run at this commit. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
