> Therefore I decided to build a lighter EPUB reading system, Bene. You're using it right now. This document is an EPUB — you can download it by clicking the button in the top-right corner.
Because, reading this on a desktop browser, I didn't even notice until it was pointed out. It's more obvious on mobile because the header takes up more of the viewport, but it otherwise behaves pretty much like a normal web page.
This is probably a good thing.
For what it's worth, I didn't see (or at least didn't notice) a spinner when loading the doc for the first time like some other people in the comments reported. I did notice it on my phone, but it went by pretty quickly. I'm not sure if that's the WASM program loading and if it only happens the first time you load the page.
