// ═══════════════════════════════════════════════════════════════════════════
// CoreError — errors surfaced by shared accounting-suite primitives.
//
// Consumer CLIs (invoice-cli, receipt-cli, …) typically define their own
// AppError with a `#[from] CoreError` variant so they can wrap and extend it.
