Kakuro / Fillomino / Masyu / Yajilin / Hashiwokakero / Nurikabe / Slitherlink / Star Battle Puzzle Generator with Uniqueness Prover

Deterministically seeded generator for eight Nikoli logic-puzzle families — each board is grown solution-first, rendered as puzzle + solution SVGs, and verified by an exhaustive backtracking solver that counts solutions to two, so “unique” is a proof (and an exhausted budget is reported as unproven, never guessed).
