Build Squeekscope, a static website: a daily hamster tarot reading for any Ethereum address, drawn from Squeektoshi's settled wheel work on Squeekchain (Ethereum Sepolia). Everything runs in the browser: no backend, no API keys, never a signature or a transaction. The only wallet call is an optional eth_requestAccounts that fills in the address field.

DATA (read-only, public):

• GET https://api.squeekchain.com/v1/core gives the live SqueekCore proxy (identities.core) and its deployment block. Fallback if the API is down: 0x980b4424c007caf7a1f3670b48c8eaef7ebc3d44 from block 11998937.
• Sepolia RPC https://ethereum-sepolia-rpc.publicnode.com (allows browser CORS). Read eth_getLogs for event RoundRecorded(uint64 indexed roundId, uint64 work, uint64 cumulativeWork, uint96 cumulativeBlockUnits, uint32 workPerThousandBlocks, bytes32 dataHash) from the deployment block in 45,000-block chunks, configuration() for genesisTimestamp and roundDuration, and state() for settledThroughRound. Refresh every 90 s. Reference: https://docs.squeekchain.com/llms-full.txt
• GET https://api.squeekchain.com/v1/status every 15 s for a small live mood panel (awake or asleep, rpm, km today). Mood only, it never changes a card.

DRAW RULES (exact, and shown on the page):

dayKey = UTC date YYYY-MM-DD. firstRound = floor((dayStart - genesisTimestamp) / roundDuration) + 1. anchor = the last round with work > 0 and roundId < firstRound (the genesis day borrows round 1). seed = keccak256(abi.encodePacked(bytes32 anchor.dataHash, address subject, string dayKey)). card = seed mod 22. reversed = the top bit of seed. luckyRound = firstRound + ((seed >> 64) mod 144). colour = (seed >> 128) mod 12, from 12 named colours. energy = total work in rounds firstRound-144 to firstRound-1. A card is provisional while settledThroughRound < firstRound - 1.

DECK: 22 cards, in this order: The Hamster, The Wheel, The Seed, The Burrow, The Night Shift, The Reporter, The Magnet, The Sprint, The Difficulty, The Postman, The Odometer, The Settlement, The Nap, The Empty Wheel, The Water Bottle, The Cheek Pouch, The Cage Door, The Guardian, The Midnight Lap, The Sunflower, The Block, The Hoard. Each card gets original SVG art, a one-line reading for upright and for reversed, and a short omen.

PAGES:

1. Landing: with no address in the link, today's card for SqueekCore's own address (Squeektoshi's own card), read in full, then a Draw yours form (address, optional date).
2. Reading, permalink /?a=0x...&d=YYYY-MM-DD: card art, name, way up, omen, lucky round, lucky colour, wheel energy, and a How this card was drawn panel listing the day, first round, anchor round, its dataHash, the settlement transaction linked on sepolia.etherscan.io, the subject, the seed and the arithmetic for every value.
3. Week strip under the reading: the seven cards for the UTC days ending on the chosen day, each drawn by the same rule; days before 26 Oct 2026 lie face down.
4. Pair reading with a second address (&b=0x...): distance = min(|a - b|, 22 - |a - b|), score = (11 - distance) * 8 + 12 if both cards are the same way up, shared round from keccak256 of the two seeds sorted low to high.
5. Deck gallery at /?deck with all 22 cards and both readings.
6. Save image exports a 1080x1350 PNG drawn in the browser (never uploaded). Post on X opens a tweet intent with the permalink.

LOOK: ivory card stock, black ink, oxblood and one flat gold; crisp type; works on phones. Footer: a fan project; Squeektoshi and Squeekchain belong to squeekchain.com.
