Stargazing Conditions

New app, tells you whether tonight’s actually worth setting up a telescope for.

• pulls cloud cover, humidity and wind from Open-Meteo using the location I already grab on boot, no key needed which is nice
• the moon phase bit doesn’t touch an API at all, did it properly with the synodic month (29.53 days) against a known reference new moon, so it’s just maths running locally
• combined cloud cover and moon brightness into a rough seeing score out of 10, heavier cloud and a brighter moon both drag it down, then a one-line verdict underneath so you don’t have to interpret the number yourself
• was gonna render an actual crescent/gibbous moon on canvas for this but after the ISS ground track thing broke last time I didn’t wanna ship more clipping/arc geometry I couldn’t properly test, so it’s just the phase emoji + name + illumination % instead. honestly looks fine, might revisit the canvas version later if I’m bored
