//! Per-network ORB DAO parameter-NFT categories — the single place to set them.
//!
//! ORB governs protocol revenue through two parameter NFTs (see libriften
//! `docs/orb.md`): a `PoolParams` NFT whose commitment pins delegation-pool fee
//! parameters, and an `IdoParams` NFT whose commitment pins IDO parameters. Each
//! NFT is identified by its **token category**, which is a per-network deployment
//! constant. A pool/IDO is only an ORB-protocol member if its init transaction
//! spends the network's live params NFT (see the `orb` / `ido` admission code).
//!
//! Categories are stored in **display byte order** (like a token id string), the
//! convention the indexer compares against (`token.id` reversed). Until a real
//! category is set, its placeholder is the all-zero sentinel — [`is_configured`]
//! is false and admission fails **closed** (no pools/IDOs admitted), never open.
