🎮 Overview NostalgicRainSystem creates a fully dynamic rain simulation with: 

 Falling rain particles (with wind + tilt) 

Splash sub-emitters on impact

 Continuous rain sound 

Random thunder sounds 

Realistic lightning flashes with configurable color Debug gizmos to visualize spawn zone

 Dynamic LOD system (auto-optimizes particle emission based on FPS)

 Works with both HDRP and URP using appropriate transparent shaders
