[elliotBraem]

What's the feature?

This is a TransformerPlugin. Want to learn how to build a plugin? Start here.

---

This transformation plugin should take in data (define your input type) and it will output an ai generated image (define your output type).

Sounds like grok has good results, although should be able to set modal and style.

This plugin might be able to take influence from the ai-transform plugin.

Acceptance Criteria

• page added to docs, following docs style. README should be copy of docs page
• pull request to main repository curate.config.json using the plugin
