Graphics / VFX

• Added progress-based brightening with a late-game “pop”
  
• Implemented along-shape particle flow with per-segment movement
  
• Guaranteed multiple visible features (core shape + outer/inner/noise)
  
• Applied curated palette themes (blue/teal/purple) with primary/secondary mix
  
• Aligned bloom/emission tint to the chosen palette color
  

Audio-Reactive

• Hooked FMOD timeline markers; secondary particles pulse on kicks.
  
• Kept primaries on steady progress-driven brightness, independent of pulses
  

Rendering / Ordering

• Fixed draw order so background particles sit behind the board background
  
• Avoided global emission overrides that homogenized colors; preserved per-particle look
  

Note: Background particles CAN NOT be disabled, I plan on introducing this as another setting switch in following updates. Also, the first song in the list does not have Kick reactions for the particle backgrounds; its a tedious process that I'm working on.
