Sky Lanterns
Dozens of glowing paper lanterns drift upward through a starlit night sky over silhouetted hills. Each lantern rises at its own speed and sways side to side on independent sine-wave phases, recycling back to ground level once it floats out of view to create an endless stream.

• 60 lanterns, each with unique speed, sway phase and scale
• Open-ended cylinder body + glowing flame sphere + point light
• Lanterns loop: reset to a low altitude after passing y=90
• 2500-star procedural sky dome with a static moon disc
• Auto-orbiting camera when idle, OrbitControls otherwise
