CV Scale Homography
Scales a 3x3 homography from one resolution to another via numpy (T(scale_a) @ H @ T_inv(scale_b)). If both images were downscaled by factor S for feature detection, set scale_a=scale_b=1/S to recover the full-resolution homography. This is a numpy helper, not a cv2 wrapper.

| Name | Type | Default | Description |
|---|---|---|---|
| homography | NPARRAY | 3x3 homography matrix (float64). | |
| scale_a | FLOAT | 1.000.000001–1000000 | Scale factor from detection-space to full resolution for image A (target/warp-ref image). 1.0 = no change. |
