      <h1>UCW Email Wallet</h1>
    </header>
    <main>
      <p>
        Create a user-controlled wallet with email OTP. After verification, the
        server returns a challenge; the browser runs
        <code>sdk.execute</code>; then the app lists the wallet address and
        balances. Uses
        <code>@circle-fin/user-controlled-wallets</code> and
        <code>@circle-fin/w3s-pw-web-sdk</code>.
      </p>

      <label>
        Email
        <input
          id="email"
          type="email"
          placeholder="you@example.com"
          autocomplete="email"
        />
      </label>

      <button id="sendOtp" type="button">Send OTP</button>
      <button id="verifyOtp" type="button" disabled>Verify OTP</button>

      <p>
        First verify: initialize challenge → wallet. Later logins: already
        initialized — list wallets only (no challenge).
      </p>

      <div class="wallets" id="walletStatus" aria-live="polite" hidden>
        <p>Wallets:</p>
        <ul></ul>
      </div>

      <pre id="log">Enter an email, send OTP, then verify (challenge → wallet on first login).</pre>
