🪄 How It Works

1️⃣ Schedule Trigger - starts the automation (e.g., hourly or daily).
2️⃣ Define Memecoin - stores your mascot metadata:

memecoin_name: popcat
mascot_description: cat with open mouth
mascot_image: https://i.pinimg.com/736x/9d/05/6b/9d056b5b97c0513a4fc9d9cd93304a05.jpg

3️⃣ AI Agent - prompts Gemini to:

• Write a short 100 character tweet in Gen Z slang.
• Create an image generation prompt inspired by current meme trends.
  4️⃣ NanoBanana API - applies your base image + AI prompt to create art.
  5️⃣ Upload & Tweet - final image gets uploaded and posted automatically.
