//! Centralized framework-aware account mapping.
//!
//! `FrameworkAccounts` maps ~45 semantic account purposes to framework-specific
//! GL account codes. Adding a new accounting framework requires writing one
//! constructor and one constants module — all downstream consumers use the
//! same struct.
