A wallet cannot pay before its free\n//         quota is used (same forced-free-first logic as Pumpkinagent).\n//       * No per-wallet paid cap besides the 420 total supply\n//         (MAX_PAID_PER_WALLET = 420).\n//   - ONLY Binance Agentic Wallet holders can mint: the contract checks\n//     the caller holds a Binance .ai Agent ID (registry balance > 0,\n//     same registry used by the ASUSAGENT/COWAGENT/SCOOBYDOAGENT/\n//     PONDAGENT contracts).\n//   - Fees ACCUMULATE in the contract (not forwarded per mint). The owner\n//     (set at deploy as a constructor argument, since deployment goes\n//     through a factory) can call withdraw() at any time to send the whole\n//     balance to the fee recipient (immutable, set at deploy).\n//   - Metadata: tokenURI returns baseURI + tokenId once the owner sets\n//     a baseURI via setBaseURI (owner-only); until then tokenURI is\n//     empty. Artwork can therefore be attached later without redeploy.\n//   - No royalties (ERC2981 not included); marketplaces apply their own\n//     royalty rules, if any.\n//   - No pause, no extra minting path, no receive/fallback:\n//     plain BNB transfers to this contract revert instead of locking funds.\n//   - NOTE: this collection is NOT affiliated with or endorsed by Matt\n//     Furie or any rights holder of Pepe the Frog. The name is used\n//     here as a fan/agent-themed label only.\n//   - NOT DEPLOYED YET.
