Detailed Description

Gradient and edge detection on normalised float image spans.

Pure functions. No MayaFlux type dependencies.

Conventions

• All inputs are single-channel normalised float in [0, 1]
• w and h are pixel dimensions; caller ensures span size == w * h
• Border handling is clamp-to-edge throughout
• Gradient angle is in radians in [-pi, pi], measured from +X axis
• Parallelism handled internally via Parallel::par_unseq
