- Pass the custom sky box to the Viewer instead of `skyBox: false`, which
also stopped CesiumWidget from creating the Sun and the Moon. Guarded by
scripts/qa-sky-sun-moon.mjs.
- Outside the IAU 2006 tables (before 1975, after ~2050) the preload
resolves without data; remember that span and stay on TEME instead of
preloading and rendering every frame.
- The anime style no longer cel-shades the far plane, where four bands
turned the faint Milky Way into blotches.
- Paint the planets out after the star-removing opening and with the
ring median, so no brighter plateau is left; faces rebuilt.

Cesium's default Tycho-2 sky box is six 1024² JPEGs stretched 3–6× around
the whole-globe view, so space read as an over-compressed JPEG (HAL-627).
The scene now draws its own sky in the Scene#skyBox slot: the 9,096 stars
of the Yale Bright Star Catalogue as point sprites sized in CSS pixels
(magnitude → width and opacity, B−V → colour), over a soft, star-free
Milky Way cube map built from ESO/S. Brunier's panorama (CC BY 4.0). Both
layers share one ICRF→Earth-fixed rotation at the scene clock, with the
TEME rotation filling in until Cesium's IAU 2006 tables load.
Assets total 482 KB, built by scripts/build-bright-stars.mjs and
scripts/build-milky-way.mjs. Frame time and the idle render governor are
unchanged.
