/* SofaList site: one stylesheet.

   Palette from the app icon: #673AB7, #D3BBFF, #F7EDFF; text in neutral near-black.
   WCAG AA contrast (normal text needs 4.5:1):
     light  #1D1B20 on #F7EDFF 15.05   #673AB7 on #F7EDFF 6.46
            #1D1B20 on #FFFFFF 17.07   #673AB7 on #FFFFFF 7.33
            #FFFFFF on #673AB7  7.33 (header)
     dark   #E6E0E9 on #141218 14.35   #D3BBFF on #141218 10.91
            #E6E0E9 on #1D1B20 13.17   #D3BBFF on #1D1B20 10.02
   #D3BBFF on #673AB7 is 4.30, so it is never text on the header (border only). */
