/**
 * MoonRenderer - Unified Moon System
 *
 * Features:
 * - Stylized procedural moon with recognizable lunar features
 * - Lunar maria (dark "seas") and prominent craters including Tycho with rays
 * - Real lunar cycle calculations (shows actual current moon phase)
 * - Configurable color temperature (warm/cool tint)
 * - Smooth glow with no banding
