//! Container types for component-level item lists.
//!
//! Each holds an `AppendOnlyVec` of one IR variant and a thin `add` method
//! that pushes and returns the items-vec position. They share the same
//! shape today; kept as separate structs because they're conceptually
//! distinct and may grow per-kind helpers as the mutation API rounds out.
