Spice up your notifications
summary
Claims a practical hack that actually displays Genmoji in notifications on iOS18 by reverse engineering the image blob, extracting the H image and its metadata, finding the required t:documentName key, and synthesizing a UIImage/attributed image with a random UUID so notifications render the custom emoji. Builds a messaging app for Mastodon, tests show notifications now show the fox emoji instead of a heart, and the proof‑of‑concept is released as Zoji (open source).
