// TestMain quiets the global zerolog level for the duration of the test
// suite. Rationale (Q-038, 2026-05-05): viper's internal watcher goroutine
// (started by viper.WatchConfig in WatchAndApply) has no public Stop and
// can outlive a test's context. Any log call from a leaked goroutine
// races with the next test's LoadConfig → SetupLogging →
// zerolog.SetGlobalLevel under `go test -race`. Disabling the logger here
// is the root-cause fix: the racing memory location is zerolog's gLevel
// global, and if no log call ever evaluates against it we sidestep the
// race entirely without changing production behavior.
//
// In production, log calls happen against an unchanging global level
// (SetupLogging runs once at startup), so the race condition does not
// occur there.
