-*** WireGuard Module
-The Waybar includes a custom WireGuard VPN status module that shows connection status, TX/RX stats, and peer info.
-
-Setup:
-
-1. Install openresolv (needed by wg-quick for DNS):
-   #+begin_src bash :tangle no
-   sudo pacman -S openresolv
-   #+end_src
-
-2. Configure sudo for wg-quick (required for click-to-toggle binds):
-   #+begin_src bash :tangle no
-   echo "$USER ALL=(ALL) NOPASSWD: /usr/bin/wg-quick" | sudo tee /etc/sudoers.d/wireguard
-   #+end_src
-
-3. Create a WireGuard config (if not exists):
-   #+begin_src bash :tangle no
-   sudo cp /etc/wireguard/work-laptop.conf /etc/wireguard/
-   sudo chmod 600 /etc/wireguard/work-laptop.conf
-   #+end_src
-
-4. Refresh Waybar to pick up new config:
-   #+begin_src bash :tangle no
-   killall -q waybar && waybar -c ~/.config/waybar/config.jsonc & -s ~/.config/waybar/style.css &
-   #+end_src
-
-Or use the launch script:
-   #+begin_src bash :tangle no
-   ~/.config/waybar/launch.sh
-   #+end_src
-
-Keybinds:
-- ~$mainMod+Ctrl+V~ — Connect WireGuard (work-laptop)
-- ~$mainMod+Ctrl+Shift+V~ — Disconnect WireGuard
-
-The module polls /usr/bin/wg every 10 seconds. It shows a lock icon with TX/RX when connected, or an unlock icon when disconnected.
