/*
 * Page layout + NES controller styling.
 *
 * The controller rules below are a plain-CSS compile of the SCSS from CodePen
 * epzilla/AqweZk (the "NES Controller"). The Compass `@import` (vendor-prefix
 * helper) and the `$red` variable have been resolved by hand; nesting has been
 * flattened; `.pressed` selectors were added so keyboard / programmatic presses
 * light the buttons the same way `:active` does for mouse/touch.
