Aether - Snow Mountain Watch Face

Aether is a pixel-art watch face for Garmin Forerunner 255, celebrating the beauty of snow-capped mountains. The scenery evolves with the time of day. • Sunrise & sunset - the snow peak glows in gold ("日照金山", alpenglow) - the signature view • Daytime - clear blue sky over a snow-capped ridge • Night - deep indigo sky scattered with stars A pixel-style digital clock sits at the center, with real-time heart rate on the right and step count on the left. The date shows weekday and day below the time. Highlights: • Three time-of-day scenes (golden sunrise / blue day / starry night) switch automatically • Pixel-art time display with subtle drop shadow • Tuned for the fr255's 260×260 MIP reflective display - Floyd–Steinberg dithering for smooth gradients in 64 colors • Low-power friendly: second-level refresh while awake, minimal updates while asleep • Battery level display • Sedentary reminder — sitting for too long triggers snowfall and snow accumulation effects.

Added support for battery level display and sedentary reminder.
