/* Jukepod -- promo page.
   One bold thing: the iPod in the hero, with a click wheel that works.
   Everything around it is quiet: left-aligned type, white polycarbonate
   panels on a cool aluminium page, and the device's own blue selection
   gradient kept for things you can press or that are selected. Green (the
   iPod's battery) only ever means "passed". */
