themes - Update colors by brand guidelines.
themes - Replace Google Maps iframe with img on phones.

    The interactive Google Maps iframe does not work very well on small
    devices.  Swapping it out for an image of the map that is wrapped in
    a link to the map itself works much better.  The image can scale and
    the user can tap to view the interactive map full-screen.  An info
    notice makes this clear to the user.
