===== - Partículas (Charge) agora têm: - beliscado: flag que indica se estão sendo puxadas para o centro. - friction: desaceleração ao serem beliscadas. =====
* Bobina (is_coil) pode: - Emitir partículas internas para fora (“chover”). - Criar ondas de mosaico visual.
* Evento de tecla (space por exemplo) ativa efeito de chover partículas.

Vou criar um esqueleto funcional que implementa essas ideias:
