Good time of day. Please advise how I can rotate the control handle so that I can perform rotation along the axis of the curve, not the global coordinate system? I need this in order to change the extrusion pitch

The Labs Curvature node produces color (@Cd) as well as float values for concavity and convexity. You can use either of those to drive a color ramp, or route @Cd, via displayColor USD tag directly to the shader.

You are the best! Thank you so much!

How do I use the curvature node in materials for Karma render? I can't find information about this task anywhere.
