Generators

Seeded maze generator API

Generates a perfect maze (one unique path between any two cells) on a WxH grid via the recursive-backtracker algorithm, returning per-cell wall flags. The value-add: stable, solvable maze layouts from a seed, with the carving algorithm done right. Answers 'Generate a maze from this seed', 'How do I build a deterministic perfect maze grid?'.
