//! Constants used by the crate.
//!
//! This module contains various constants used throughout the crate, including:
//!
//! - Seeds for deriving Program Derived Addresses (PDAs)
//! - Program account addresses and public keys
//!
//! The constants are organized into submodules for better organization:
//!
//! - `seeds`: Contains seed values used for PDA derivation
//! - `accounts`: Contains important program account addresses

/// Constants used as seeds for deriving PDAs (Program Derived Addresses)
