   app.css — Q-Optimization

   A work tool that building operators read on office screens, so LIGHT is
   the default and dark is opt-in. The palette is the Quwa family: the cyan
   brand (#0b7592 on light, #19c8e8 on dark), the green arrow of the mark for
   "good", amber for "waiting", coral for "needs attention". Every colour is
   a token; nothing below hard-codes a hex.
