Same preliminary base as the other Flower base page, but built on a different foundation: instead of a hand-derived rotation formula for every fold, most points here are found by a small physics-style solver — every original paper edge is a fixed-length constraint, a handful of points are driven each step, and everything else is discovered by the solver from rigidity alone. This is the base for adding new folds (like petal folds) without re-deriving closed-form geometry each time.
