Usage: $(basename "$0") [options]

Installs Sunshine + Moonlight on an Omarchy machine.

Options:
  --no-autostart    Don't enable user service or lingering (manual start only)
  --no-firewall     Skip firewall configuration
  --no-moonlight    Don't install moonlight-qt (host-only setup)
  --no-sunshine     Don't install sunshine (client-only setup)
  --no-config       Don't write a tuned sunshine.conf
  --from-source     Build Sunshine from source (equivalent to SUNSHINE_PKG=sunshine)
  --headless        Force headless streaming mode (wlr capture of HEADLESS-1)
  --mirror          Force mirror mode (KMS capture of the real display)
  --no-certs        Skip the 1Password-backed cert step (use Sunshine's self-signed)
  --force-certs     Re-mint the host cert even if the current one is valid
  --doctor          Run only the post-install verification checks
  -h, --help        Show this help

Environment overrides:
  SUNSHINE_PKG       AUR package to use for Sunshine (default: sunshine-bin)
                     Set to 'sunshine' to build from source instead.
  OP_VAULT           1Password vault that holds the root CA (default: Private)
  OP_CA_ITEM         Item title in that vault (default: Omarchy-Stream Root CA)

     (Self-signed cert — accept the browser warning.)

  3. On a Moonlight client (this machine, the Framework, or your Mac):
       - Add this host by IP: ${BOLD}${ip:-<your-lan-ip>}${RESET}
       - Enter the 4-digit PIN that Sunshine's UI shows during pairing.
