got rid of a bunch of m[l/r/x/y]-x tailwind classes and used more
flex-[row/col] gap-2's. UI should be more consistent in general, and
with the admin UI.
The page you were on is actually read from the URL on reload, however
does not keep settings (implemented just for ease of UI editing,
really).
`missing-colors.js` preprocessor script now applies dark prefixes for
<section>s, but like with cards, does not apply a default ~neutral to
those without, so that <section class=""> looks different to <section
class="~neutral">.
Light/dark selector added to setup too, and the actual mode given to the
browser through CSS `color-scheme` is correct, meaning things like textareas, checkboxes and
controls are now colored according to the theme.
all theme functionality is now in theme.ts, and the tab stuff has been
changed a little but kept in admin as it won't be in use anywhere else
for the time being.
the web ui has been redesigned with the a17t toolkit, which imo looks a
lot better than bootstrap. This also brought a complete rework of the
web code, which now makes a lot more sense hopefully. the setup page is
still stuck with bootstrap, its not much of a priority but i'll rewrite
it eventually.
