A 60x60 circular dial drawn at the top-center of the screen shows the current position in the day/night cycle. A filled arc sweeps clockwise from the top; the color transitions from dark blue (night) through orange (dawn), gold (day), and pink (dusk). A small glow dot marks the leading tip; a phase label (Night/Dawn/Day/Dusk) sits below. Redraws only when the cycle fraction changes. References DayNightCycle via node_path so it stays in sync with the environment lighting.
