//! Client-side Wake-on-LAN: parse stored MAC strings and hand them to the shared core sender
//! (`punktfunk_core::wol`). A sleeping host has no ARP entry, so the broadcast the core sends is
//! what actually wakes it; this is called just before connecting to an offline saved host and
//! from the explicit "Wake host" menu item.
