Struct StartupBanner 

pub struct StartupBanner { /* private fields */ }

Builder for structured startup banners printed to stderr.

Collects lines and prints them as a formatted block with header, sections, and footer separators. All output goes to stderr so it is visible in k8s logs even before the tracing subscriber is initialized.
