/* Jonathan Roberts Gas Heating & Plumbing, Liverpool — shared stylesheet.
   Brand taken from his own van: a black vehicle, a white wordmark, and an
   orange house outline with a tap inside it. No logo file exists (the profile
   picture is a photograph of the van bonnet), so the wordmark is type and the
   house-and-tap idea is redrawn as a simple orange frame. */
