This setting is fixed at program startup time, and can't be modified
by changing the `GODEBUG` environment variable after the program starts.

Go 1.24 changed the global [`math/rand.Seed`](/pkg/math/rand/#Seed) to be a
no-op. This behavior is controlled by the `randseednop` setting.
For Go 1.24 it defaults to `randseednop=1`.
Using `randseednop=0` reverts to the pre-Go 1.24 behavior.
