Replace the flat billboard-disc planets with real 3D EllipsoidGraphics spheres textured with self-hosted high-res NASA/JPL + Solar System Scope maps (hd_*.jpg, 2048x1024), plus a PlaneGraphics Saturn ring (top-down annulus, transparent centre, depth-tested occlusion). Constant axial tilts (Venus upside-down, Uranus on its side). Cesium gotchas handled: constant orientation (time-varying orientation drops image materials -> blank white); DirectionalLight intensity 0.42 (no HDR -> higher clamps bright maps to white); camera.flyTo is dead in this mode so enter/travel run a manual eased setView tween (flyCamera); ellipsoid+ring gated by distanceDisplayCondition(r*30) so the orrery overview stays clean colored dots and the textured sphere takes over up close. Drop 9 now-unused 2k_ maps; textures/ is 3.3MB. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com>
