/*
  Desktop layout
  The previous rule constrained the entire document to 430px whenever the
  viewport was wider than a phone. Besides creating the "mobile page in the
  middle of desktop" effect, it also prevented the product gallery from using
  the available space. The product page now changes layout at tablet/desktop
  widths while keeping the compact phone experience above.
