/* ==========================================================================
   shell.css : reset, page frame, top bar, module switcher, sidebar, footer.
   Written left to right first, then mirrored for Arabic with [dir="rtl"].

   Second revision. One light top bar replaces the old stacked pair of dark
   navy bars, and the sidebar is now light with a hairline border. The
   module bar is gone: module switching lives in a single control in the
   top bar, which removes a whole band of competing links from every page.
