- Eliminated the .flush-top class on <hr>s on the About page since we want the styles applied to all About page <hr>s.
- Color schemes should match the bottom border of active tabs to the scheme's body-background variable.
- Lighten the comment background color on the Dashboard activity widget to keep adequate contrast with the new lighter body background.
