//! Equipped-component selection for the TTX engine.
//!
//! A [`ShipUpgradeSelection`] names, per `ShipUpgradeInfo` slot, which upgrade is
//! mounted. The TTX component maps ([`super::components::ShipTtxComponents`]) are
//! keyed by these same upgrade names, so the orchestration entry point resolves
//! each component by looking the selected name up in the matching map.
//!
//! Slots a ship lacks (e.g. a carrier's artillery/torpedo/fire-control slots, or a
//! gunless ship's artillery) carry `None` and produce a `None` stat section.

/// The upgrade mounted in each TTX-relevant `ShipUpgradeInfo` slot.
///
/// Names are the `ShipUpgradeInfo` keys (e.g. `PAUH911_Gearing_1945`), which is how
/// [`super::components::ShipTtxComponents`] keys its maps. Secondaries are not a
/// separate slot: the ATBA component is referenced by the hull upgrade, so the
/// secondary map is keyed by [`Self::hull`].
