.chm (compiled html) is the best readable file format

I made a thread about this before and everyone went full stockholm syndrome and tried to defend .epub even though that is a shit format that turns every book layout into something that is worse than the typewriter.

.chm is lightweight, supports links, the layout is zoomable and changes layout when you resize it. Its an extremely light weight format, very rare for it to go over 3mb
