Build "ActorTrust Ledger" in ONE Lovable message. Single-page demo.

CONCEPT
Store and verify actor resumes and roles securely with social login and no gas fees.
Discipline: Theater & Live Performance (performance credentials).
Onchain primitive: Privy social + sponsored tx. Why this primitive: Privy social offers identity verification; sponsored tx allow easy credential updates.

5-CREDIT BUDGET (HARD LIMIT):
- ONE single-page app. No router, no Lovable Cloud, no database, no auth flows beyond Privy drop-in.
- ONE Solidity contract, <=80 lines, deployed to BSC Testnet, verified on BscScan.
- Privy is the auth + embedded-wallet layer (Google login, wallet auto-provisioned).
- Gas is USER-PAID. There is NO sponsorship on BSC Testnet in this template — the user needs a small tBNB balance from the faucet. Surface a "Get tBNB" faucet link in the UI.
- Pinata/IPFS only if the idea genuinely needs to store a file or metadata.
- At most ONE AI call per user action (use Lovable AI Gateway with LOVABLE_API_KEY if AI is part of the idea).
- Skip tests, skip CI, skip docs pages. Ship the demo, nothing else.

STACK
- React + Vite single page (the index route).
- SSR-safe Privy mount is mandatory. Never import @privy-io/react-auth at
  module scope of a route file — it crashes SSR. Use
  lazy(() => import('./privy-client-entry')) inside <ClientOnly> + <Suspense>,
  and put <PrivyProvider> only inside privy-client-entry.tsx.
- PrivyProvider config uses viem's `bscTestnet` chain (chainId 97):
    import { bscTestnet } from 'viem/chains';
    <PrivyProvider appId={import.meta.env.VITE_PRIVY_APP_ID}
      config={{ loginMethods:['google','email'],
                embeddedWallets:{ ethereum:{ createOnLogin:'users-without-wallets' } },
                defaultChain: bscTestnet,
                supportedChains: [bscTestnet],
                appearance:{ theme:'dark' } }}>
- Read the embedded wallet from useWallets, not user.wallet:
    const embedded = wallets.find(w => w.walletClientType === 'privy');
- Every send goes through Privy `useSendTransaction` with `chainId: 97` and
  `address` (NO `sponsor` — BSC Testnet is user-paid in this template):
    await sendTransaction(
      { to, data, chainId: 97 },
      { address: embedded.address }
    );
- Do NOT pass uiOptions:{ showWalletUIs:false } — it aborts with
  "signal is aborted without reason". The approval sheet is expected on
  the embedded-EOA path; the user pays a tiny tBNB fee.
- Do NOT add ZeroDev / SmartWalletsProvider / a paymaster URL. This
  template is intentionally user-paid on BSC Testnet.
- USER FUNDING: the embedded wallet needs a small tBNB balance. Show a
  "Get tBNB" link next to the connect button pointing at
  https://www.bnbchain.org/en/testnet-faucet. Catch "insufficient funds"
  errors and re-surface the faucet link inline.
- Hardhat in /contracts (kept outside the Vite bundle). Install
  `@nomicfoundation/hardhat-toolbox` AND `@nomicfoundation/hardhat-verify@latest`
  (>=3.x — older versions still hit Etherscan v1 and fail with
  "You are using a deprecated V1 endpoint, switch to Etherscan API V2").
- hardhat.config.cjs uses the Etherscan v2 single-key shape with a
  customChains entry pointing v2 at BscScan (chainid=97):
    require("@nomicfoundation/hardhat-toolbox");
    require("@nomicfoundation/hardhat-verify");
    module.exports = {
      solidity: { version: "0.8.24", settings: { optimizer: { enabled: true, runs: 200 } } },
      networks: { bscTestnet: {
        url: process.env.BSC_TESTNET_RPC_URL || "https://data-seed-prebsc-1-s1.bnbchain.org:8545",
        accounts: [process.env.METAMASK_PRIVATE_KEY.startsWith("0x")
          ? process.env.METAMASK_PRIVATE_KEY : "0x" + process.env.METAMASK_PRIVATE_KEY],
        chainId: 97,
      } },
      etherscan: {
        apiKey: process.env.BSCSCAN_API_KEY,
        customChains: [{
          network: "bscTestnet",
          chainId: 97,
          urls: {
            apiURL: "https://api.etherscan.io/v2/api?chainid=97",
            browserURL: "https://testnet.bscscan.com",
          },
        }],
      },
      sourcify: { enabled: false },
    };
- Deploy: `npx hardhat run scripts/deploy.cjs --network bscTestnet`.
- Verify: `npx hardhat verify --network bscTestnet <address>` — verified source
  appears at `https://testnet.bscscan.com/address/<address>#code`.
- Frontend reads: create a viem public client on bscTestnet using the same RPC —
  `createPublicClient({ chain: bscTestnet, transport: http(import.meta.env.VITE_BSC_TESTNET_RPC_URL) })`.
  Cap `getLogs` ranges to `fromBlock = head - 9000n`; the public RPC rate-limits wider windows.
- Write the deployed address to `src/data/contract.json` so the UI links to
  `https://testnet.bscscan.com/address/<address>`.

USER FLOW
1. Land on page -> 'Sign in with Google' (Privy) -> embedded wallet auto-provisioned on BSC Testnet.
2. Prompt user to fund with tBNB (faucet link) if balance is zero.
3. Every performance credentials action the user performs is sent as a BSC Testnet tx (`log(payload)`) via Privy's embedded wallet and displayed with a BscScan link. Show a small 'need tBNB?' faucet link the first time the user hits a low-balance error.
4. Footer renders: "Built during the Creative AI & Quantum Hackathon organised by StreetKode Fam during Indian Krump Festival 14"
