   tinkytown-demo Bottom Nav — demo-bottom-nav.css
   --------------------------------------------------------------------------
   Companion to js/demo-bottom-nav.js. Visual parity with the kiosk's
   bottom-nav (Home / Numbers / Translate / Events). Numpad modal styling
   lives here too since it's only opened from this nav.
