/*
  StepCivics website (stepcivics.app).
  Colors are Teal, StepCivics' default theme, from the "StepCivics — UI Design" canvas, light and dark.
  The backdrop is a shade deeper than the app's #0B6869 (#09595B) and the glows stay faint, so captions
  and gradient titles keep 4.5:1 wherever they sit. Type is Inter only, served from /fonts.
  Approved design: the "StepCivics — Website Design" canvas.
