   guess.css — styling for the "guess" frontend (guess.html / guess.js).

   The guess mode reuses the whole soup shell (viewport + burger menu + optimize
   dock). It is a copy of soup.css so the two can drift independently; the only
   real difference is the prompt: instead of an editable prompt box, the dock
   shows a hidden ("masked") prompt display that is only unblurred once the user
   presses Reveal. The guess-specific rules live at the very end of the file.
