I've updated the website https://www.canonic.com to make it into a html landing page and moved the actual app to https://app.canonic.com.
Hopefully now if you are on a platform or browser with less than stellar WASM support (MacOS / mobile) you can now at least view the website to see what Canonic is about.
A user over on r/browsers suggested I turn it into a progressive web app (PWA) so that it can actually be installed which may be the next move. It would save me a lot of work dealing with sandboxing, at least for now. I'm not sure if Qt users would see that as heresy though :)
Various other bug fixes and performance changes have also been made.
