    <li>You may contribute any amount (0–{{ C.ENDOWMENT }}) to a shared fund.</li>
    <li>The fund is multiplied by {{ C.MULTIPLIER }} and then split equally among group members.</li>
    <li>Your payoff = ({{ C.ENDOWMENT }} − your contribution) + your share of the multiplied fund.</li>
    <li>One shot (no repeats in this demo). Decisions are private.</li>
  </ul>
  <p><strong>Example:</strong> if each of 3 players contributes 20, the total is 60. Multiplied by the efficiency factor and split equally, each participant receives an equal share from the fund. Your payoff equals your kept amount plus your share.</p>
