The "Referral Race" Campaign Writer

Act as a viral growth manager. Help me write the copy for a competitive referral campaign where the top referrer wins a major prize.

• Prize: [e.g., "$500 Gift Card"]
• Time Limit: [e.g., "One week"]

Task: Write the announcement email and landing page. Explain the rules of the competition clearly. Include a leaderboard to foster competition. The copy should be highly energetic and competitive, urging customers to refer their friends to win.
