It is in the image! Along with the other settings. The A1111 web UI or other compatible tools should pull it out.
For anybody confused: The Lemmy version of the image (the one with pictrs in the URL) won't have it, it strips out the EXIF data (or wherever else the prompt is stored). You have to download the image from catbox (click on the title, not the thumbnail), which seems to keep the data.
While I went through the effort I may as well throw it in for future reference:
