@ -14,6 +14,7 @@ This is a NixOS flake-based configuration for multiple hosts:
- `home-manager/` — Home Manager configuration (via NixOS module)
- `services/` — modular service definitions, gated by hostname with `lib.mkIf`
- `settings/` — shared settings (desktop, hyprland, quickshell, stylix, …)
- `walls/` — wallpapers. Each gets a dark base16 palette generated at build time; the shell picks one at runtime (bar button → `settings/quickshell.nix`), so switching re-tints the shell without a rebuild. `walls/wallpaper.png` stays the build-time stylix scheme for everything else.
- `modules/crowdsec/` — vendored crowdsec modules from nixpkgs PR #446307; delete once that PR lands in the pinned channel
- `ports.toml` — WAN → LAN port forwards consumed by `services/router.nix`
