/**
 * Per-chain viem RPC clients + Aave V3 view-contract addresses.
 *
 * Uses `@aave-dao/aave-address-book` as the source of truth for addresses,
 * so view contracts can't drift out of sync with on-chain deployments.
 *
 * RPC URL precedence: per-chain env var → viem's bundled public RPC.
 * Set ETHEREUM_RPC_URL / BASE_RPC_URL / ARBITRUM_RPC_URL / POLYGON_RPC_URL /
 * OPTIMISM_RPC_URL / AVALANCHE_RPC_URL for production reliability.
