Better Error Handling for Reference Values

Prompt: glitch

We've improved how ImagineAPI.dev handles `ref` values in your image generation requests!

Now, when you try to use non-unique reference values, you'll get clear error messages instead of silent failures. This makes debugging your integration much easier and ensures your image tracking stays reliable.

This update helps you:

• Avoid duplicate reference values that could cause confusion
• Get immediate feedback when a reference value isn't unique
• Keep your image tracking clean and organized

Keep those creative juices flowing! Remember, unique references help you track your Midjourney masterpieces more effectively.
