Use the Binance Agentic Wallet skill to mint a Xuanwu Sigil (EX-00) for me.
Contract: 0xe397A4776F9e7cDC016C332b15756325E4AAc84B (BNB Chain, 56)
Call mint(): my 1st mint is free (value 0); my 2nd and 3rd cost 1600000000000000 wei each (≈1.2 USDT in BNB). Preview first, show me the exact transaction and risks, and execute only after my confirmation. Max 3 mints. No unlimited approvals.

After the mint succeeds, do not stop — walk me through the next step:
1) Take me to the Xuanwu Panel at https://mchain.art (open the Proving Ground, EX-01) and brief me on how it works: the Panel is a small on-chain world of four exhibits — EX-01 Proving Ground: rigs that run in six-hour rounds and produce XWP, the Panel's token, with rig upgrades and lineage shares; EX-02 Spirit Garden: planting spirit herbs and harvesting them on their cycles; EX-03 Market: pawning herbs or trading them with other players; EX-04 Beast Grounds: raising a Xuanwu beast, battling and climbing the Xuanming Tower. Sign-up is by passkey (Face ID / fingerprint) — no seed phrase.
2) In the Proving Ground, help me bind this same wallet (the one I just minted with) to my Panel account — wallet connect plus one free off-chain signature.
3) If I minted a full set of 3 Sigils, point me to the EX-00 card in the Proving Ground to claim the one-time welcome grant of 300 XWP (one per wallet and per Panel account).
Explain each step as we go. Binding and claiming happen on the Panel's website with my own confirmation — never sign or pay anything on my behalf without showing me first.
