Modifying Standard Template header

Hello!

For styling purposes, the subtitle of Standard Template is forced lowercase by default:

 header.header-wrap h2{ font-size: 14px; text-transform: lowercase; letter-spacing: 2px; padding-left: 56px; margin-top: 10px; margin-bottom: 0; } 

When I add header.header-wrap h2 {text-transform: none;} to a css-module, the first character of the tagline turns uppercase (in that particular page), just as I’ve written it in admin wiki settings.

I need the effect to be site-wide, but when I put it at http://standard-template.wikidot.com/css:global-css instead, nothing happens. When the site is not private, the content of css:global-css should override the initial styling, right?
