extends Node3D

## Test scene: Sky3DExtended atmosphere + SunshineClouds2 volumetric clouds.
## Sky3D Extended provides atmosphere/sun/moon/stars/cirrus.
## SunshineClouds2 provides volumetric cloud rendering via CompositorEffect.
##
## Controls:
##   T / Shift+T  — advance / rewind time by 1 hour
##   F            — fast forward (1min cycle)
##   G            — normal speed (15min cycle)
##   P            — pause / resume time
##   F12          — screenshot
