- Modular flake-based architecture
- Parameterized user configuration (username, timezone, locale, etc.)
- Classical/antiquity theme with Thomas Cole wallpapers
- Full Hyprland setup with waybar, rofi, swaync
- Custom utility scripts (screenshots, screen recording, WiFi QR)

- Interactive installer for existing NixOS systems
- ISO builder for fresh installations

Flake outputs:
