Type Alias LogHandler 

pub type LogHandler = Arc<dyn Fn(&str) + Send + Sync>;

Runtime configuration for the HTTP server adapter.

The HTTP adapter keeps environment-specific concerns, such as the storage root and authentication secret, outside the Core transformation API. Tests and embedding runtimes can construct this value directly, while the CLI entry point typically uses ServerConfig::from_env to load the same fields from process environment variables. A logging callback invoked by the server for diagnostic messages.

Adapters that embed the server can supply a custom handler to route messages to their preferred logging infrastructure instead of stderr.
