/* Singbud app theme: the homepage's look (css/home.css) carried into the app. Loaded after every other sheet.
   Near-white ground with pale cyan waves, navy text, teal actions, one coral accent, pill buttons, Outfit and Lexend.
   The older sheets all read these tokens, so most of the change happens here at the top.
   --coral was the app's action colour, so it now holds teal; the real coral accent is --accent. */
