   GymPilotIQ.Web — application styles

   Deliberately hand-written rather than pulled from a framework: the whole
   stylesheet is smaller than a CSS framework's gzipped header, and it lets the
   web app match the phone app's dark/cyan identity exactly rather than
   approximately.

   The colour variables are the MAUI app's Colors.xaml, one for one.
