/* styles.css — how everything looks.

   The app uses the Xero Point Racing colours and nothing else:
     XPR      yellow      #eeee22
     XFINITE  light blue  #30abe2
     XNOVA    purple      #8729cc
   all on carbon black, with greys and white for everything quiet.

   What each colour is used for:
     yellow      the main colour: buttons, what is selected, what is happening now
     light blue  good news: done, ahead, finished
     purple      things that need attention: warnings, errors, running out of fuel

   Pit stops use none of the three: they are white on the dark theme and black on the
   light theme, like the white stripe on the cars, so they never clash with a driver's colour.

   The lists below hold every colour: one list for the dark theme, one for the light
   theme. Change a colour there and the whole app follows. */
