//! Parse-time TTX component base stats.
//!
//! These structs hold raw GameParams values for ship components (hull, engine,
//! and later torpedoes/artillery) read straight off the ship dict during parsing.
//! No formulas or modifier coefficients are applied here; the query-time factory
//! layer converts these into unit-carrying stats and folds in the equipped
//! `ModifierBundle`. Retaining typed `f32`/`Option` values (not the raw pickle)
//! keeps the GameParams footprint comparable to the sibling `HullUpgradeConfig`.
//!
//! Reference-chain (gun/ammo) component stats for torpedoes and artillery are
//! added by later milestones; this module currently covers hull and engine.
