-# pawdance.sh – EXACT client *and* server logic driven by an easy‑to‑edit config file
-# -----------------------------------------------------------------------------
-# Modes (ROLE in config):
-#   client – brings up a point‑to‑point tunnel by SSH‑w’ing into the server.
-#   server – creates the matching tunnel locally and (optionally) enables routing.
-#
-# Connection source (CONNECT_MODE):
-#   dns   – resolve REMOTE_HOST on every run.
-#   ip    – use the hard‑coded REMOTE_CONNECT_IP4 and/or REMOTE_CONNECT_IP6.
-#   auto  – if REMOTE_HOST is set use dns, otherwise ip (default).
-#
-# Extra dial options:
-#   CONNECT_PREFER   – which address family to try first (auto|ipv4|ipv6).
-#   SSH_KEY_MODE     – set to "true" to pass an explicit private key via -i.
-#   SSH_KEY          – absolute path to that key (required if SSH_KEY_MODE=true).
-#
-# -----------------------------------------------------------------------------
-# v4.5.1 – better --help, commented example configs, SSH_KEY_MODE support.
