//! Framework-mode prelude for authored Hopper programs.
//!
//! This import is intentionally small: account wrappers, instruction context,
//! common wire types, result/error types, guard macros, CPI/token facade modules,
//! and the canonical proc macros. Protocol-grade state machinery lives behind
//! `hopper::systems::*` or explicit modules such as `hopper::segment`.
