Styling: Consider not using such a less intense background color

[twavv]

The current background color is really perceptible (i.e., you notice it) and it should maybe be toned down.

As an aside, the background-color should be applied on the body element (it's currently applied on a div, presumably in _app.tsx or wherever we define the default page layout) so that scrolling past the edge (the browser will "snap back", but still show you that bit beyond the edge of the actual content) doesn't show white.
