1// ⚠️ L'AVERTISSEMENT « filter under a transform that never stops moving » EST ASSUMÉ ICI.
2// Les astéroïdes portent une lueur et pulsent en `sin`, donc leur composite filtré est recuit à
3// chaque frame. Retirer le `sin` ferait taire le message SANS rien changer : ils tournent aussi en
4// continu (`rotation = time*0.7`), ce qui décale leur position à l'écran tout autant — la règle ne
5// vise que les motifs périodiques, elle ne voit pas la rampe. Le seul correctif réel serait de
6// retirer le `filter`, et le halo néon est précisément le sujet de cette démo.
