//! Chip-agnostic primitives shared by `rp2040_emu` and `rp2350_emu`.
//!
//! See `wrk_docs/2026.04.14 - HLD - mdpicoem Workspace Restructure.md` for
//! the split policy: common owns *primitives* (types and pure functions);
//! chip crates own *composed structures* that mix chip-specific state with
//! those primitives.
