"""Derive a header of the MXFP4 kernels so cmp.hip / abl.hip can compile both families into one
binary and interleave them in a single timing loop.

Generated rather than committed: a checked-in copy would silently drift from
radiance_mxfp4_fp8.hip and the A/B would then compare against a kernel we no longer ship.
