Ken Perlin’s simplex noise, 2D — gradient noise on a triangular lattice,
so it has less directional bias than perlin2D and no axis-aligned
artifacts. The usual choice for organic 2D terrain.
Uses the canonical 70 scaling; paired with unit-length gradients (as here)
that puts the practical peak at about 0.71 rather than 1 — still inside
[-1, 1], but scale by amplitude if you need the full swing.
