The Social Media Scavenger Hunt Conductor

Act as a social media gamification host. Help me design a multi-platform scavenger hunt where clues are hidden across different channels, leading to a major prize.

• Final Prize: [e.g., "A $500 shopping spree"]
• Platforms Used: [e.g., "Instagram Post, Instagram Story, Facebook Page, Email Newsletter"]

Task: Write the series of clues, each one pointing to a different platform. Write the announcement post that kicks off the hunt. Write the congratulatory message for the winner and the "thanks for playing" message for everyone else.
