Add Stylix as a flake input and a desktop theming module that resolves a single Nord base16 scheme across the graphical surface: GTK, Qt, cursor, and the system monospace font, plus a static Nord wallpaper drawn as a Polar Night gradient. Scope the theming to the graphical layer alone. The Stylix targets for fish (at both system and home-manager level), tmux, and nixvim stay off so the terminal tools keep their hand-written themes.
