Set page background color to accent

[corywatilo]

Since the footer is bg-accent, we should make the page background bg-accent (so we don't have tan space below the footer on short pages), but this also means we'll need to add a tan/dark background color to all content within the page to make sure accent doesn't bleed through.

I can not reproduce this issue.
Seems it has already been fixed in another PR.
