common.css ships the neutral Remarkbox light palette for all themes. The
chaostheory dark palette and dark re-skins (.alert-*, section.well, .focused,
etc.) now live here in theme.css, which loads after common.css and overrides
:root for chaostheory pages only.
Matches core remarkbox base.j2 behavior (request.path == '/' and
namespace.google_site_verification set). Needed for Google Search
Console verification of foxhop.net when app.theme = chaostheory
replaces the default base template.
