  THEME: keystone
  PURPOSE: Default F.R.I.D.A. Timer theme — dark navy with cream panels
  DESCRIPTION: Dark navy body background (matching F.R.I.D.A. 2.0 landing page
                  hero section) with cream/tan panels and buttons for contrast.
  NOTE: Fonts are defined in layout CSS files via CSS variables --font-primary
        and --font-display. This theme explicitly resets to layout defaults.
