This commit includes many bug fixes and improvements to the admin UI.
More errors are caught and displayed to the user. Submit buttons now
display a loading state while the request is being processed. Several
inconsistencies and style issues in the admin UI have been fixed. Image
upload inputs now have an accurate accept attribute, so tat users cannot
upload images that are unsupported. Finally, in development mode, the
page is outlined in dashed yello to help me not go insane when I forget
that I'm using the deployed site and thats why my changes arent doing
anything, and the API returns 400 errors when images are unsupported
formats.
In this realease, I have further optimized Passport. The css that
Passport now uses is entirely handrolled and build via postcss (sadly).
Several bugs have also been fixed in this release, as well as a few
performance improvements relating to the admin UI.
