 - SSH is preferred; telnet is available only if explicitly enabled and should be disabled on untrusted networks.
 - When audio is muted the script points libao to the `null` backend to avoid opening `/dev/dsp` or Pulse pipes.
 - Landlock sandboxing provides extra filesystem isolation when available. The script downgrades gracefully when the kernel is too old.
