//! **GUNNAR_CLOCK* read as ESTATE_CLOCK*** in the real process environment
//! (lane G3b): a Gunnar medium baked with `korp.env.GUNNAR_CLOCK=` and
//! `korp.env.GUNNAR_CLOCK_KEY=` keeps its clock on estate-clock. Its own test
//! binary, ONE test: it sets the process environment, which no other test sees.
