The harness excludes artifacts/ from Git on purpose and uploads it separately, so the layout is as intended. The task is complete.

What was delivered

• site/ is now a Vite + TypeScript project (no framework, no wallet library) with the live launch addresses and stackerDeployBlock 11874601 in site/public/config.json. projects.json stays [].
• dist/ holds the committed production export with relative asset URLs, 56 kB total.
• The page keeps the previous scope and adds what the brief asked for: per-button pending, success and error states, a network badge with a "Switch to Sepolia" button, light and dark themes with a toggle, a recent-stacks table, and plain-language translations of contract errors.
• DESIGN.md documents the tokens, typography, components and responsive behavior of the final source.
• The README has the three addresses with explorer links, install, preview, rebuild and publish steps, and a validation summary.
• artifacts/validation.md records the review across all six Better Interface domains, four fixes made and rechecked, commands run, and screenshots in artifacts/screenshots/.

Checks that ran

• Typecheck and production build both exit 0 after the last source change.
• ABI hashes from forge build match all three abiHash values in deployment.json.
• Live Sepolia reads in Chromium: vault open, zero events scanned from the deploy block, no console errors, all resources loaded from a subpath.
• No horizontal overflow at 320 px and 360 px. Focus rings visible. Both color schemes rendered.

Two limitations you should know about

• The faucet, approve and credit transactions were exercised in the real browser, but against an anvil fork of Sepolia at the live addresses with an injected test wallet. No funded Sepolia key exists on this machine, so nothing was broadcast to Sepolia itself. All observed states, including the stack and leaderboard updates, are recorded in the validation file.
• No IPFS pinning tool or credentials exist here, so the page was not pinned from this machine. artifacts/hosting.json names the label imd-acc-test, the dist/ directory, and the locally computed CID for the publisher to pin.

Local servers were stopped and node_modules removed; nothing is left running.
