Parastichy-34
A Vogel sunflower: each seed at the golden angle 137.508° with radius proportional to √n. The eye finds 21 and 34 spiral families — consecutive Fibonacci numbers, the closest rational approximations to φ. Eighty-nine CSS seeds. No canvas.
- 137.508°

The packing plants already solved
Gold conic ticks mark the 34-family; cyan ticks mark the 21-family. They counter-rotate so the parastichies lock and unlock — a living proof that φ is the least-rational rotation.

θ_n = n · 2π/φ² · r_n ∝ √n · families F₈=21, F₉=34 · N=89=F₁₁
89 is itself Fibonacci. Hue walks 148°→313° so the disk is a chloroplast, not a kaleidoscope. CSS
sqrt() places the seeds; a fallback uses linear radius where sqrt() in transforms is missing.
