/**
 * Creates a seeded pseudo-random number generator using the mulberry32 algorithm.
 * Produces deterministic float values in [0, 1) for a given seed.
 *
 * @param seed - Integer seed. Pass Date.now() for natural randomness in production.
 * @returns A function that returns the next random float in [0, 1) on each call.
 *
 * @example
 * const rand = seededRandom(42);
 * rand(); // always the same sequence for seed=42
