What a great idea! When testing this out, the text from the articles is somewhat opaque, which makes it difficult to read. The images and headers seem look fine though.
I’ll update the colour to be a full black colour for when digests get sent out so this doesn’t happen
Edit: I just updated the fonts to just render in black for the article body so the text should be all black in your next digest
Also setting the journal prompts to black would be wonderful - they are hard to see unlike the articles.
