SunArc: Solar & Lunar Widget

SunArc redefines timekeeping by merging the precision of modern clocks with the natural paths of the sun and moon. It is an advanced celestial visualizer that calculates the journey of the stars across your specific horizon and renders it as a minimalist piece of home-screen art.

🏛️ THE CONCEPT
Most clocks tell you when to be at a meeting; SunArc tells you where you are in the day—and the night. By combining Solar and Lunar Relative Time with Wall-Clock Time, SunArc provides a unique dual-perspective on your location's cosmic rhythm. Whether you are tracking the "Golden Hour" for photography, the moon's phase for stargazing, or simply want to stay in sync with the Earth's rotation, SunArc transforms your device into a refined celestial instrument.

✨ KEY CAPABILITIES

🔭 CELESTIAL MODELING & RENDERING
• Solar & Lunar Calibration: Calculates the exact moment the sun and moon reach their zenith based on your precise coordinates.
• High-Fidelity Rendering: Advanced engines simulate atmospheric light scattering (Solar Bloom) and soft lunar glow.
• Real-Time Moon Phases: Track the moon’s cycle from New to Full with scientifically accurate illumination and tilt (parallactic angle).
• Eclipse Intelligence: Stay ahead of the cosmos with automatic detection and visual alerts for upcoming Solar and Lunar eclipses, calibrated to your specific path of visibility.
• Dynamic Horizon Geometry: Choose between a modern "Horizon View" or a technical "Pie Slice" view that adjusts with the seasons.

🎨 DESIGN & CUSTOMIZATION
• Dual Rendering Engines: Choose "Physics Mode" using Rayleigh scattering models for realistic atmospheric effects, or "Artistic Mode" for high-contrast, OLED-optimized palettes.
• Unique Visual Styles: Select from High-contrast Light, Deep Night, and Glass-Transparent themes.
• Hybrid Analog: A classic 12-hour face synced to any location's wall-clock time.
• Lunar Detail: Fine-tune your moon experience with customizable Moon Glow, New Moon visibility, and scale.

🌍 GLOBAL INTELLIGENCE
• Search Anywhere: Track any city or landmark worldwide using our integrated location engine.
• Independent Widgets: Every widget on your home screen can track a different city with its own unique visual theme.
• Automated Timezones: Intelligent detection ensures your clock always follows the correct local time and Daylight Savings rules.
