   Brand tokens are lifted from drivenmidland.ca so this app reads as part of
   the same family: the red #BE1D2C, Source Sans Pro, and square corners
   (the parent site sets border-radius: 0 on almost everything).

   Everything visual is defined by the custom properties in :root. A reskin —
   including Joe's final design — is a change to that block, not a sweep
   through the file.
