A generative arrangement of 1000 circles follows a phyllotaxis spiral, offset by an irrational angle derived from 1+√2. Each circle is colored with a warm sequential scale from D3, and the innermost circle briefly turns transparent in sequence via a timed activeCircle index, creating a wave-like fade. Rendered as SVG within a Svelte component, the layout is computed by a custom `layoutPhyllotaxis` function using D3’s `scaleSequential` and `interpolateWarm` for color mapping, with smooth CSS transitions animating the opacity changes.
