/* components.css. The parts every page shares: header, footer, buttons, panels, inputs, the sign-in dialog.
   Loaded after tokens.css and base.css, and after each page's older stylesheets.
   The header and the footer use their own class names (sg-...), so they work on every page.
   Buttons, panels and inputs are restyled only on pages that have moved to the new design, they carry
   class "sg-page" on <body> (added by _tools/build_site.py). Game and admin pages keep their older look
