// blank override at boot, so a running process never actually hits the
// fallback in production; it exists so every caller — including template
// render tests that build page data directly, without going through
// cmd/start.go's viper.SetDefault — gets a safe, non-blank name.
//
// Registered as the "deploymentName" template func everywhere operator.html
