Build "AnimPitch Fund" in ONE Lovable message. Single-page demo.

CONCEPT
Pitch animation projects to decentralized investors with onchain proposals and funding escrow.
Discipline: Filmmaking & Animation (project pitching).
Onchain primitive: Plasma smart contract. Why this primitive: Plasma smart contracts ensure transparent funding and project milestone tracking.

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 Plasma Testnet, verified on Plasmascan.
- Privy is the auth layer (Google login, embedded wallet). Users pay their own gas in XPL.
- 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).
- Target chain is **Plasma Testnet** (chainId 9746, native token XPL, ~1s blocks,
  full EVM). RPC: https://testnet-rpc.plasma.to. Explorer: https://testnet.plasmascan.to.
  Faucet: https://openfaucet.org/.
- Define the chain inline for viem (Privy accepts any viem chain, no built-in export needed):
    const plasmaTestnet = {
      id: 9746, name: 'Plasma Testnet',
      nativeCurrency: { name: 'XPL', symbol: 'XPL', decimals: 18 },
      rpcUrls: { default: { http: [import.meta.env.VITE_PLASMA_RPC_URL || 'https://testnet-rpc.plasma.to'] } },
      blockExplorers: { default: { name: 'Plasmascan', url: 'https://testnet.plasmascan.to' } },
    } as const;
- 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 — pass the plasmaTestnet chain via supportedChains and
  defaultChain so the embedded wallet lands on the right network:
    <PrivyProvider appId={import.meta.env.VITE_PRIVY_APP_ID}
      config={{ loginMethods:['google','email'],
                supportedChains:[plasmaTestnet], defaultChain: plasmaTestnet,
                embeddedWallets:{ ethereum:{ createOnLogin:'users-without-wallets' } },
                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 `address` and
  `chainId: 9746`. Do NOT pass `sponsor: true` — Privy's native gas sponsorship
  does not cover Plasma; users pay their own XPL. Wrap the call in a 45s
  Promise.race timeout that tells the user to top up XPL if their balance is 0:
    await Promise.race([
      sendTransaction(
        { to, data, chainId: 9746 },
        { address: embedded.address }
      ),
      new Promise((_, r) => setTimeout(() => r(new Error(
        "Plasma tx timed out. Check the embedded wallet has XPL from https://openfaucet.org/"
      )), 45_000)),
    ]);
- Preflight: before calling sendTransaction, read the wallet's XPL balance via
  a viem publicClient({ chain: plasmaTestnet, transport: http() }). If it's 0,
  render a toast + inline banner with a copy-address button and a link to
  https://openfaucet.org/ so the user can drip XPL to themselves.
- Do NOT pass uiOptions:{ showWalletUIs:false } — it aborts with
  "signal is aborted without reason". The approval sheet is fine.
- Do NOT add ZeroDev / SmartWalletsProvider / any paymaster URL. Plasma
  Testnet uses simple EOA transactions.
- Hardhat lives in /contracts (kept outside the Vite bundle). Install
  `@nomicfoundation/hardhat-toolbox` and `@nomicfoundation/hardhat-verify@latest`.
- hardhat.config.cjs — Plasma Testnet network + Plasmascan (Etherscan-compatible) verify:
    require("@nomicfoundation/hardhat-toolbox");
    require("@nomicfoundation/hardhat-verify");
    module.exports = {
      solidity: { version: "0.8.24", settings: { optimizer: { enabled: true, runs: 200 } } },
      networks: { plasmaTestnet: {
        url: process.env.PLASMA_RPC_URL || "https://testnet-rpc.plasma.to",
        accounts: [process.env.METAMASK_PRIVATE_KEY.startsWith("0x")
          ? process.env.METAMASK_PRIVATE_KEY : "0x" + process.env.METAMASK_PRIVATE_KEY],
        chainId: 9746,
      } },
      etherscan: {
        apiKey: { plasmaTestnet: process.env.PLASMASCAN_API_KEY || "empty" },
        customChains: [{
          network: "plasmaTestnet",
          chainId: 9746,
          urls: { apiURL: "https://testnet.plasmascan.to/api",
                  browserURL: "https://testnet.plasmascan.to/" },
        }],
      },
      sourcify: { enabled: false },
    };
- Deploy: `npx hardhat run scripts/deploy.cjs --network plasmaTestnet`.
- Verify (right after deploy, no constructor args for these contracts):
  `npx hardhat verify --network plasmaTestnet <address>`
  Source becomes readable at `https://testnet.plasmascan.to/address/<address>#code`.
- Frontend reads via viem: `createPublicClient({ chain: plasmaTestnet,
  transport: http(import.meta.env.VITE_PLASMA_RPC_URL) })`. Expose the RPC to
  the client by also setting VITE_PLASMA_RPC_URL to the same value.
- Write the deployed address to `src/data/contract.json` so the UI links to
  `https://testnet.plasmascan.to/address/<address>`.

USER FLOW
1. Land on page -> 'Sign in with Google' (Privy) -> embedded wallet auto-provisioned on Plasma Testnet.
2. If wallet XPL balance is 0, show the openfaucet.org top-up banner with copy-address.
3. User performs a project pitching action; the app calls `log(payload)` on the contract via the Privy embedded wallet and shows the Plasmascan link as proof.
4. Footer renders: "Built during the Creative AI & Quantum Hackathon organised by StreetKode Fam during Indian Krump Festival 14"
