Some styling elements were, apparently, specifically designed for the Dark Theme. And while all voters as of yet use the Dark Theme, it would be helpful for other users if a proper Light Theme styling is developed.

Many high-activity wikis are well-maintained in this regard among other things, so anyone interested in a better Light Theme design could ask someone knowledgeable they know to adjust the styling for this wiki too.

Alternatively, the dark-themed elements, namely -- most/all infoboxes, many/some tables, could be re-designed (or set to default), but that would affect those who primarily or exclusively use the Dark Theme.

Anyone wishing to apply a properly developed Light Theme styling, create an example in your sandbox page and post a link to it here.
