A complicated-looking orbit becomes two circles.
IDWT starts with A = cos(Lθ)eⁱθ and B = sin(Lθ)eⁱθ, pairing the four coordinates.
Combine them as (A+iB)/√2 and (A−iB)/√2. The sine and cosine merge into pure rotations at rates L+1 and −(L−1).
Result: two circles of radius 1/√2, with squared radii adding to 1.
