//! Integration: a fully-populated `SanthError` renders one actionable message
//! that joins title, fix, context, and location, with a secret in the source
//! chain redacted - exercising the builder, `compose_message`, and `redact`
//! together rather than any one in isolation.

use santh_error::{ErrorLocation, SanthError};
