🪔 Lights Festival Mode (Diwali Special)

Celebrate virtual Diwali in the Lights Festival Mode. Arrange traditional oil diyas, compose geometric rangolis, hang paper lanterns, and release glowing sky lanterns.

1. Traditional Diwali DIY Decoration

Use coordinates from `FestivalOfLightsScreen.kt` to arrange traditional lights and decorations:

• 🪔 Diyas (Oil Lamps): Select Clay, Brass, Floral, or Royal diyas. Tap to place them on terraces or ghats, and watch their flame particles flicker dynamically.

• 🏮 Hanging Lanterns (Kandils): Hang Cylinder, Globe, or Diamond lanterns that sway in the wind.
• 🪂 Sky Lanterns: Release Classic, Royal, or Festive paper lanterns that float into the night.
