Gnomon The Moon
A moon detail screen whose crescent is drawn from the illuminated fraction itself, so a 4.7 percent waxing crescent genuinely looks like one, with the age against the synodic month, the month ahead as eight computed phases, and the one thing an observing night cares about: the moon set before the dark began.

The rule this design follows
It ships exactly as previewed: same colors, same type, same copy, same motion. The prompt tells your agent to build that, and not to adapt it to your existing theme.
