Office windows now render a living sky: night with stars, a moon, and lit
city windows; a warm sunrise; blue daylight with the sun arcing across; and
an orange sunset - all interpolated smoothly along a palette timeline driven
by the actual clock, over a per-window deterministic skyline. Phase mapping,
sun/moon handover, star intensity, and palette blending are unit-tested.
