herbaceousBranchingPolicy distinguishes monopodial, sympodial, and polypodial
axis behavior. createInflorescence produces generic sockets for racemes,
spikes, panicles, umbels, cymes, and capitula with terminal flowering and
maturation times. updateBud models dormancy, activation, death, and conversion
to flowers using resource and apical-signal inputs.
createRadialFlower exposes petal geometry, while sepals, stamens, centers, and
custom organs remain structural groups/factory concerns rather than a fixed art
style.
