Project: https://hamsterhour.fun

Maintenance update of the existing Hamster Hour site (current build: https://hamster-hour-bet-on-the-wheel.sites.imd.fun, served at https://hamsterhour.fun). Keep design, layout, copy, contract wiring, wallet flow, chat, History, Settle, Stake and TEAM pages exactly as they are. Change only the five items below.

Contracts (Ethereum mainnet, unchanged): HamsterHour 0xc5217f129da200a8e86229de4eabf3686eef64b1, OracleVerifier 0xdcd7a7dee31d589f9df8113780050c18e7ea1f7d. Deployment record and ABIs are already in the site (/imd-deployment.json, /abi/*.json).

1. Bet sheet amount field. In every bet sheet (OVER, UNDER, SLEEPING/RUNNING, EXACT) the "IMD" suffix inside the amount input wraps onto two lines ("IM" / "D") on desktop and mobile. Make the suffix white-space: nowrap with a min-width, let the number input shrink instead. Verify at 375px and 800px.

2. Plurals. "1 messages" -> "1 message", "poked 1 times" -> "poked 1 time"; keep plural for other values. Apply to every counter on the site.

3. Jackpot copy. Hide the sentence "The jackpot pays only if the closest guess is within 2% of the result." (EXACT sheet) and the line "Available jackpot: Not enabled yet." (How it works) while HamsterHour.jackpotToken() is the zero address. Conditional render, show them again once the token is configured.

4. Live window progress (new, small). While the current window is running (windowTimes(k).startsAt <= now < endsAt), show a block under the countdown card: "Window k in progress · round r of 6 · N passes so far · line L" and a thin progress bar N / L (cap 100%).

Data only through the existing Hamster Hour worker (same base URL the site already uses for /live and /status); never call squeekchain.com directly (CORS):

• GET {worker}/status -> measurement.cumulativeWorkUnits (decimal string, live hardware counter; keep the current 20 s polling).
• GET {worker}/rounds -> mirror of Squeekchain /v1/settlements?range=now. Use recentSettlements[] (up to 10, newest first): previousSettledThroughRound, settledThroughRound, cumulativeWork, workAdded. All decimal strings, parse as BigInt. Round mapping: Squeekchain genesis is 1791847800 and its round n covers [1791847800 + (n-1)600, 1791847800 + n600). Do not reuse HamsterHour.genesisTimestamp for this mapping, it can differ by one round. firstRound = floor((startsAt - 1791847800)/600) + 1, lastRound = firstRound + 5. Round shown to the user r = clamp(floor((now - startsAt)/600) + 1, 1, 6).

baseline = cumulativeWork of the settlement with settledThroughRound == firstRound - 1. passesSoFar = cumulativeWorkUnits - baseline, clamped at 0. If that exact settlement is not in the list, use the newest one with settledThroughRound < firstRound and prefix the number with "≈"; if none, show only "round r of 6". Also show the block inside "My bets" for a bet on the running window. Mobile: one line, bar below.

Small print under the block: "Live counter, unofficial. Result is settled by the IMD oracle."

5. First visit. Expand "How it works" by default on the first visit (remember collapse state in localStorage, default collapsed afterwards).

Deliver the updated site in the same hosting slot, no new dependencies, bundle size roughly unchanged. Test at 1280, 800 and 375 px: bet sheets, How it works, History, TEAM page read-only without a wallet, progress block with a running window and with the hamster asleep (N = 0).
