/**
 * Network × asset matrix for x402 `exact` accepts.
 *
 * Honesty rules:
 * - Default active accept = primary Base USDC (dev: Base Sepolia) — Render-safe.
 * - CDP facilitator “live” networks per docs (Base, Polygon, Arbitrum, Solana, …).
 * - Optimism / BSC / Ethereum: config-ready asset addresses; facilitator-dependent.
 * - TRON: planned only — never emitted into `accepts[]` (no scheme in current deps).
 * - Solana: experimental stub unless operator opts in (`ACCEPTS_JSON` / `NETWORKS` + payTo).
 *
 * USDC: https://developers.circle.com/stablecoins/usdc-contract-addresses
 * USDT: Tether / chain explorers (bridged where no native); BSC-USD is 18 decimals.
 * CDP: https://docs.cdp.coinbase.com/x402/network-support
