Xenon-gtk is a dark, colorful GTK3 theme designed to complement the Xeno KDE theme. Xenon-gtk does not currently support GTK4 or desktop environments other than KDE.

Features:
- Dark mode
- Gradient accents
- Frameless
- Rounded corners
- CSD similar to Xenon Aurorae window decoration (as a graceful fallback when SSD are unavailable)
- Close/Min/Max buttons grow when hovered, and glow when pressed
- Active windows glow, inactive windows have an inverted shadow (window edges are always apparent)
