This plugin was generated by Gemini 2.5 Pro with the following prompt:
Create a WordPress plugin which does the following:
Create a new postmeta field in WordPress which contains an array of colors names. This gets stored as serialized data in one postmeta value.
Expose this as postmeta field so it is publicly accessible and editable via the REST API for any user who has the ability to edit posts.
On the frontend, when a user is logged-in and is able to edit a post, print out a JavaScript function in an inline script which fetches that REST API field to log out to the console, and then create another function which calls the REST API to update that postmeta field.
