A monochrome lunar study uses phase-like discs as data containers. Designed for the Garmin Forerunner 255 and 255 Music, it shows time, date, battery level, steps, and current heart rate in a distinctive, glanceable layout.

Version 1.3.0: refreshed typography, semantic icon treatment and presentation assets aligned with Vector Momentum while preserving Lunar Grid's layout, settings and supported devices. Simulator previews use Garmin-native values; metric availability depends on the watch, firmware and recorded samples.
