I've got streams being set properly for each category. The last bit is to clean up the content automatically and rewrite / swap out image tags. Particularly photos posted with Sunlit. Posts made with Sunlit are displayed as an <a> tag (which links to your original image with a "-scaled" suffix) and an <img> tag with a source that proxies through micro.blog.

It also has an attachment of the second photo, which I am automatically inserting into the post.

I need to extract all <a> tags, detect if their href attribute has a "-scaled" in it, and strip that. Then I can look in my database for that attachment entry in my db and rewrite the tag as a Tanzawa image insert. Shouldn't take too long. Maybe tomorrow.
