`log1p(|cx|) (i.e. log(1 + |cx|)`, finite at zero) min-max normalised to
`[0, 1]`. This is the conventional way to see a spectrum whose linear
magnitude is dominated by the DC spike. Display only — it is not invertible;
use :func:cx_magnitude for the metric magnitude.
Typed bridge of the 2d op `cx_log_magnitude into the 2-D evolution registry: the same implementation, called under the op(v, a, b) convention. This op has no tunable parameter; a and b` are unused.
