Pattern Field Theory — Light: 3D polarization ⇄ 2D π-streams

Green = out-of-plane component. Zero on the flattened side; steady wave on the restored (3-D) side.

Outward journey (3D → 2D, flattening)

3D polarization (left) gradually flattens into 2D π-streams (right).

2D π-streams (left) are restored to 3D polarization (right) near stronger gradients.

Reverse (restoration on left)

Loop animation (2D flattening ⇄ 3D restoration)

The green trace is the out-of-plane component: it is restored (to 3D) as it transitions into a gravitational 3D field.
