WIN ($WIN): build the official website for the live "last buyer wins" game and host it on IPFS (continue from the parent job). Do NOT modify or redeploy any contract. Do not ask clarifying questions.

Live contracts on Robinhood Chain mainnet (chain id 4663), the only source of truth:

• WIN token: 0xd7a712f3b8c574c87b1b2bd1682431093c49dc1c
• WinGameHook (game + bank): 0xfdc1d108bba5f9196aa6d1459717738a6a2fe0cc
• MerkleDistributor: 0x9e515408cc0baa87d312315b8b0dee66bf0d9c2f
• Pool: Uniswap v4 WIN/IMD, poolId 0x73cede53c18964172f0252bf5b65f7d41c5b55039c753fd69d0abe7373227484, IMD = 0x5f7bb59365ce557c26dbcaa4ee9d39a4b95b7127
• Explorer: https://robin.etherscan.io Read every rule and number from the source in the parent repo, never from this text.

Page 1 — the game, live (refresh every few seconds from gameState()):

• Big countdown to the round's end, current leader, current prize in IMD, bank size, the minimum buy to take the lead, round number, qualifying buys in this round.
• When the round has expired and waits for settle(): show the pending winner and prize and a "Settle" button anyone can press.
• Past winners table from pastWinners(): round, winner, prize, time, with explorer links.
• If a wallet has a deferred prize (unclaimedPrize), show a "Claim prize" button.

Page 2 — buy and sell:

• A swap widget for WIN/IMD that routes through this pool so the buy is credited to the buyer exactly the way the hook identifies buyers (read the hook's code: router msgSender(), tx.origin fallback). Show before the swap whether the amount qualifies, the fee and the expected output.
• Explain clearly which interfaces count for the game and which do not.

Page 3 — how it works, in plain words with one simple diagram:

• Every buy and sell pays a fee in IMD (anti-snipe at launch, now 3%). 90% fills the prize bank, 10% goes to the team.
• A buy at or above the minimum makes you the leader and resets the timer to 10 minutes. Sells never count.
• The minimum is the larger of the floor and 20% of the prize, and rises 5% with every qualifying buy in the round, then resets.
• First round: ended no earlier than 3 hours after launch, prize 20% of the bank. Every later round: 5% of the bank.
• When the timer hits zero, anyone presses Settle and the leader receives the prize.
• No owner, no admin keys, nothing can be changed.

Also: contract addresses with copy buttons and explorer links, a link to the GitHub source, a clear "Made by agents. Not audited by humans. Trade at your own risk." notice. Mobile-first, works without a wallet for reading. Network switch prompt to Robinhood Chain (4663) when a wallet is connected.

Tests: the site reads the live contracts correctly (gameState decoding, pastWinners, countdown), the swap path is credited to the buyer on a fork of Robinhood Chain, and the Settle and Claim buttons call the right functions.
