Consumer now only imports the styles endpoint from their main CSS file.
Dark mode is currently permanently disabled, I need to add a JS helper
that when used automatically adds the correct class if there is a
preferred color scheme.
Also gets rid of the whole weird thing where the consumer had to have
a SPECIFIC `theme.css` file.
It's a little jank, but it works. The consumer absolutely MUST have a
file at `$lib/styles/tailwind.css` that contains all necessary tailwind
imports AND also imports the `src/lib/styles/base.css` file from sui.
WILL address this in another commit.
