1//! Support's one outbound port (hand-authored, user-owned) — the optional seam where a ticket becomes
2//! delivery work. Support holds only this trait + its own DTOs; a composing service wires the real
3//! backbone-project behind it. **Zero normal Cargo edge** to project — the two Tier-4 modules stay
4//! independent (brief §7), and the DTOs are the wire contract, duplicated per consumer by design.
5//! Support posts no GL and has no ledger seam; escalation just spawns a delivery Project.
