/*
  KoiHub theme: Frutiger Aero meets Android Market.
  Glossy green header, sky gradient with bubbles and a grass hill, frosted glass panels,
  shiny rounded app icons, split-gradient buttons. Light and dark.

  Re-tint it with two variables on :root (hue numbers 0-359):
    --h   main color (header, buttons, links, hill), default 100 (green)
    --sk  sky color (background), default 200 (blue)

  Dark mode follows the system, or force it with data-theme="dark" or "light" on <html>.
  Add class "gloss" to any .icon for the shiny highlight.
  Fonts: Nunito (headings) and Noto Sans (body), loaded below.
