- 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.
