Generate images for social cards

[danhannigan]

Look into a solution for generating social images for all of our pages - plenty of great examples out there like this one: https://spacejelly.dev/posts/how-to-generate-personalized-social-media-cards-for-landing-pages-with-next-js-cloudinary/

Ideally we'd find something free, since our volume isn't super high, but I can be convinced to chip in some cash if needed.
