punktfunk-host installed.
  1. Add yourself to the 'input' group for virtual gamepads:
       sudo usermod -aG input "$USER"     # then re-login
  2. Pick a backend config (gamescope is the no-desktop default on SteamOS/Deck):
       mkdir -p ~/.config/punktfunk
       cp /usr/share/punktfunk/host.env.bazzite ~/.config/punktfunk/host.env
  3. Enable the host:
       systemctl --user enable --now punktfunk-host

NOTE: encode is NVENC-only. Install 'nvidia-utils' on an NVIDIA host. An AMD Steam Deck is NOT
      yet supported — it needs a VAAPI (hevc_vaapi) encoder backend (see packaging/arch/README.md).
