//! Module: icrc::live::fetch
//!
//! Responsibility: expose cohesive live ICRC fetch owners and shared query context.
//! Does not own: source traits, synchronous runtime adaptation, report construction, or output.
//! Boundary: keeps account, history, and capability host calls behind one internal facade.
