✅ Correções e melhorias:
* Evita divisão por zero tanto no centro quanto entre partículas.
* Partículas agora possuem massa, aumentando a “seriedade” dos movimentos.
* Impulso ao centro e interações ríspidas no mosaico continuam.
* Partículas internas (“pastas de aflição”) geradas em colisões.
* Mantidas cores, brisa e botões transparentes.

Se quiser, posso ainda adicionar um efeito visual de “brilho/energia” a cada impulso ou colisão, mostrando o “joule” de cada interação, para tornar a simulação ainda mais dinâmica.

Quer que eu faça isso?
