//! Lightweight abstraction over values that can be viewed as atoms.
//!
//! The trait keeps generic APIs flexible without forcing callers to allocate owned atoms.
//! It is used heavily by builders and arithmetic helpers so they can accept owned atoms,
//! borrowed views, and inline packed values through one entry point.
