1 Optional runtime libraries — DjVu requires djvulibre; SVG rendering is enhanced via librsvg and Cairo when available (falls back to Qt's built-in renderer otherwise)

2 Limited support — basic layout and text are shown, but complex formatting, embedded objects, and some styling may not render correctly
