A 3D torus-knot curve (`@TorusKnot(p, q, ...)`) used as the sweep path for a star cross-section (`@StarProfile`). The sketch plane is snapped to the curve's start with `@CurvePlane`, so the profile stays perpendicular as it sweeps along the interwoven path. With `p=3, q=8` the path weaves over and under itself in a classic Celtic pattern.
