# HakaseOS

A modular, flake-based NixOS configuration for a single host (`hakase`). Heavily inspired by [OmarchyOS](https://omarchy.org/).

## Features

- **Hyprland** compositor with UWSM (systemd session management)
- **Matugen** for automatic system-wide theming from wallpaper colors
- **Multi-monitor support** for intuitive desktop management
- **Hardened Firefox** with custom bookmarks and new tab page
- **Vim keybindings** throughout the system
- **SOPS** for encrypted secrets management
- **CachyOS kernel** via chaotic-nyx for performance optimizations
