type-two e9b687d983 feat: Solar System mode — real 3D lit planets + Saturn rings 
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.
