//! FIRE Bond Position Token — NFT receipt for bonding positions
//!
//! Each instance represents a single bond. Created by fire-bonding
//! via factory cellpack on bond(). User holds 1 unit as proof of ownership.
//!
//! Fields: fire_amount, start_time, end_time, claimed
//! Only the bonding contract (vault) can update claimed via SetClaimed.
