Title: Update Stylus stylesheets with CSS-like syntax

Braces, colons, and semicolons are added. Other refactoring is intentionally
omitted to keep the diff as straightforward as possible.

Testing is easy.

1. Verify that the formatting looks good
2. Verify that the old Stylus files and the new Stylus files compile to identical CSS (`diff -r` makes this easy)
