Hmm thanks, but yea a word editor would probably be missing a ton of layout and image features. The closest I've found was Scribus but it seems pretty rough.

Yes, I tried Inkscape, but sadly found its UI very unintuitive. Also bc it only works with SVG files, it doesn't properly support CMYK colours.

I know of Krita, but I mostly use Photoshop for image editing, not painting. And it's the one of the three I use the rarest and has the most alternatives, so my main pain points are the other two, as long as the three programs work well together. (Which is another weakness in FLOSS software, they don't tend to come in "suites". Not to say that Adobe apps don't have a ton of little inconsistencies and idiosyncrasies, but at least they can smoothly work with each other's files.)

My main concern would be how to prevent tampering with archived pages - the owner of the second most popular site after Wayback Machine, archive.is, has been known to modify the content of archived pages for petty personal reasons. And without the sanctity of archives, the whole exercise loses its value as proof of records of the past.

software with 1:1 feature parity with Adobe InDesign, Illustrator and Photoshop (except genAI crap)
