Thanks for building this package, super helpful.

Small flag:

In this function:

Zt = (r, t, e) => {
    const { quotient: a } = he(t, 5);
    if (r < a) return e.level0;
    if (r >= a && r < 2 * a) return e.level1;
    if (r >= 2 * a && r < 3 * a) return e.level2;
    if (r >= 3 * a && r < 4 * a) return e.level3;
    if (r > 4 * a) return e.level4;
  };

if (r > 4 * a) return e.level4;

should be

if (r >= 4 * a) return e.level4;

Currently, when t = 50, 40 is returned as undefined and hence a black square.
