// Drop this into ~/.config/slosh/config.kdl (a running session picks it up when
// you save), or point $SLOSH_CONFIG at this file. To hang it off a pane state
// instead of every pane, put the same pass inside one:
//
//     states { bell { ... } }
//
// Lub-dub, then a rest: `abs(sin())` over a full turn is two humps, and the window
// mask leaves 1.2 seconds of nothing after them. A pane that is alive and has
// nothing to say, which is most of what a long-running one is -- so it belongs on
// a state rather than on everything:
//
//     states { suspended { ... } }
