/* ============================================================================
   Documentation.

   Moved out of the template. It used to live in a <style> block nested inside
   base.html's own <style>, which closes the outer element at the first
   </style> — so the whole page sheet was being appended to base's, and CSS
   error recovery silently ate the first rule every time. (.gradient-dot was
   the casualty here; nothing looked broken because components.css happened to
   declare it too.)

   As a linked sheet it also loads after ui-system.css, so these rules now win
   the cascade instead of losing to it at equal specificity.
