Build a single-page interactive web game and Sepolia on-chain utility called "Squeek Raid: Wheel-Powered Boss Dungeon & Tester Terminal" for Squeekchain.

Core Concept: Turn Squeektoshi the hamster's real hardware wheel telemetry and Sepolia on-chain rounds into a community Boss Raid RPG, combined with an on-chain Squeek NFT squad builder and a real Sepolia contract interaction terminal.

1. Live Hardware & Chain Telemetry Engine (CORS public APIs, auto-refresh every 12s with graceful fallback so the UI never blanks):

   • Fetch GET https://api.squeekchain.com/v1/status:
     • Read measurement.coreStatus ("SPINNING" or "IDLE"), measurement.rpmMilli, measurement.speedMmPerSecond, measurement.distanceMm (convert mm to km), measurement.cumulativeWorkUnits.
     • Read builder.anchor.blockHeight, builder.anchor.blockProgress (divide by 1e9 for percentage 0-100%), builder.anchor.settledThroughRound, builder.anchor.workPerThousandBlocks.
     • Read signer.kind ("trust-m"), signer.keySlot ("0xE0F3"), modules[0].driverId ("usb-rp2040-a3144e-lm393"), and signer.lastSignature to display a "Hardware Proof-of-Hamster Verified (Infineon Trust-M)" badge.
   • Fetch GET https://api.squeekchain.com/v1/settlements?range=24h:
     • Read summary.workAdded, summary.completedBlockCount, summary.settlementCount, buckets[] (24 hourly buckets for a custom Canvas bar chart), and recentSettlements[] (with links to https://sepolia.etherscan.io/tx/{transactionHash}).
   • Fetch GET https://api.squeekchain.com/v1/economy/state:
     • Read supply.totalMintedBaseUnits (divide by 1e18 for SQK supply), staking.totalNftPower, staking.sqkPerPower, and nft.basePower[] (levels 1 to 10) and nft.cooldownBlocks[].

2. Main Gameplay — Wheel-Powered Boss Raid & Tactical Stance Game:

   • Boss Raid Arena: Feature 3 selectable pixel-art dungeon bosses ("Block Eater Golem", "Sloth Leviathan", "Latency Dragon"). Boss HP and shield phases react dynamically to live cumulativeWorkUnits, 24h workAdded, and live wheel speedMmPerSecond.
   • Active Player Gameplay (fully playable whether the hamster is SPINNING or IDLE):
     • Players lock in a Tactical Raid Stance for the current 10-minute SqueekCore round:
       • "Overclock Wheel" (Bonus multiplier when live rpmMilli > 0 or next settlement adds work)
       • "Night Watch Bastion" (Generates steady defensive Raid Points and charges a Counter-Attack meter while hamster is IDLE/sleeping)
       • "Block Breaker Surge" (Predicts whether the next settled batch completes >= 1 new Squeek block)
     • Include an interactive "Live Raid Combat & Wheel Burst Simulator" where players can trigger tactical skills, rhythm-click wheel boosts, and test their NFT squad's DPS against the boss in real time, earning persistent localStorage Raid XP, Rank Tiers, Loot Badges, and a live combat log.

3. On-Chain Squeek NFT Squad Builder (Live SVG Art & Power Calculator):

   • Allow players to assemble a 3-hamster Raid Squad by entering any Squeek Token IDs from 1 to 9999 (or clicking "Summon Random Squad", defaulting to IDs #1, #42, #888 on load).
   • Fetch GET https://api.squeekchain.com/v1/squeeks/{id} for each squad member:
     • Render the real on-chain SVG artwork directly from metadata.imageDataUri, and display metadata.name, level, basePower, mergeState, custody.owner, and traits from metadata.attributes[].
     • Squad total basePower directly buffs the player's attack power in the Boss Raid Arena.
   • Include a Merge & Staking Power Calculator implementing the official protocol formula W = P + S * (1 + P/1000) / c (where c = 40 SQK per power) and displaying the 10-level merge pyramid and cooldown blocks.

4. Sepolia On-Chain Tester Terminal (Real Web3 Wallet Transactions on Sepolia Chain ID 11155111):

   • Connect injected EIP-1193 browser wallet (window.ethereum) and provide a button to switch/add Sepolia network (chainId 0xaa36a7).

   • Provide 3 real, one-click Sepolia on-chain contract interactions using raw eth_sendTransaction and eth_call (no external web3 libraries required): a) "Ping SQK Token (Approve 0 SQK — Unlocks Tester Badge)": Send a transaction to official SQK Token (0x5501e1fa81be1c3f49225fa7668da0245d07db60) calling approve(address spender, uint256 value) with data "0x095ea7b30000000000000000000000004b67b739dfd832f4eac67a7aa3bc244fb74cea4f0000000000000000000000000000000000000000000000000000000000000000".

     b) "Claim Free Test Squeek NFT (0 ETH)": Send a transaction to official SqueekTestDispenser (0x1ff6485abfbb2d183cd673d78e1ab31c098e04dd) calling claim(uint256 quantity = 1) with data "0x379607f50000000000000000000000000000000000000000000000000000000000000001".

     c) "Trigger Mining Checkpoint": Send a transaction to official SqueekMining Proxy (0xcd46990f8349057335289ef282c276204b6cdc62) calling checkpoint() with data "0xc2c4c5c1".

   • Display transaction status and clickable links to https://sepolia.etherscan.io/tx/{hash}.

5. Visual & Engineering Standards:

   • Aesthetic: High-craft dark dot-matrix LED arcade UI (#08080A background, #121318 cards, warm gold #F8A838 & cyan #2FD6E8 accents, crisp monospace numbers, animated SVG spinning hamster wheel and pixel boss sprites).
   • Pure static zero-dependency files (index.html, styles.css, app.js, README.md). No external JS/CSS CDN libraries, zero console errors, mobile responsive (390px+), and English / 中文 language switch in header.
