Lethal Circuit

1. Complete revamp of cyberpunk neon circuit visuals. Rainy-night lighting, circuit textures and neon glow effects have been enhanced to create more immersive vibes.
2. Unified the mechanical sci-fi aesthetic for all UI elements. Buttons, popups and board borders follow a cohesive design language.
3. Retouched bomb, flag, red cross error and heart health icons, making them far easier to distinguish.
