//! Snapshot normalization helpers for integration tests.
//!
//! Responsibilities:
//! - Normalize CLI output so snapshots stay deterministic across terminals and dates.
//! - Bind `insta` settings shared by CLI snapshot suites.
//!
//! Does not handle:
//! - Creating queue fixtures or subprocess execution.
//!
//! Invariants/assumptions callers must respect:
//! - Date normalization intentionally targets `YYYY-MM-DD` spans only.
//! - ANSI stripping is limited to simple SGR color sequences used by CLI output.

/// Normalize CLI output for stable snapshots.
