Butterfly Garden (2D)

This 2D companion to the 3D butterfly garden keeps the same flight-and-rest behavior model — curved Bezier flights toward a flower, a feeding pause with a folded flutter, then a new random flower — but views it from directly above so every path is legible at once. Butterfly count and flower density are exposed as sliders instead of being fixed at ten and twenty-four, so you can crowd a small patch of flowers with a swarm of butterflies or spread a handful of them across a large meadow and watch how flight paths lengthen and rest stops thin out.
