/**
 * Chain definitions for Lux Exchange.
 *
 * Source of truth: ~/work/lux/genesis/configs/inventory/brand-l1-2026-06-05-reset.json
 *
 * 18 endpoints — 5 brand L1s (hanzo, zoo, pars, spc, osage) × 3 envs
 * (mainnet, testnet, devnet) + Lux primary C-Chain × 3 envs.
 *
 * Brand L1s share Lux primary-network validators (network IDs 1/2/3) and
 * each carries its own EVM chainId per env. RPC pattern:
 *   https://api.lux.network/ext/bc/<brand-or-C>/rpc        (mainnet)
 *   https://api.lux-test.network/ext/bc/<brand-or-C>/rpc   (testnet)
 *   https://api.lux-dev.network/ext/bc/<brand-or-C>/rpc    (devnet)
 *
 * NEVER conflate primary networkId (1/2/3/1337) with EVM chainId (per-subnet,
 * per-env). See user CLAUDE.md "Network ID vs EVM Chain ID — NEVER CONFLATE".
