// The shipped example is what package-windows seeds a runtime generate file
// from and what the setup wizard copies, so a literal budget in it is not
// documentation: it is the value every install starts with. It also DISABLES
// the measurement, because seedHardwareBudgets only fills a knob that is still
// zero (overrides.go) - a written 7 is indistinguishable from a user who chose
// 7. That shipped pair is how a 16 GB card ended up budgeted at 7 GB, and a
// 16 GB box at a 24 GB RAM ceiling it could never honour. Both knobs must stay
// commented out; pin one only by editing this test too.
