    <h3>Public Goods — Rules</h3>
    <ul>
      <li>Group size: {{ C.PLAYERS_PER_GROUP }}. Each participant receives {{ C.ENDOWMENT }} points.</li>
      <li>You may contribute any amount (0–{{ C.ENDOWMENT }}) to the shared fund.</li>
      <li>The total fund is multiplied by {{ C.MULTIPLIER }} and then split equally among all group members.</li>
      <li>Your payoff = ({{ C.ENDOWMENT }} − your contribution) + your equal share of the multiplied fund.</li>
      <li>Decisions are private and this demo has a single round.</li>
    </ul>
    <p><em>Reminder:</em> Contributing increases the group total (and everyone’s share), while keeping points increases your private amount.</p>
