One of tmux's built-in pane arrangements.

<p>An enum rather than a string, and not for tidiness: {@code select-layout} with a name tmux does
not recognise <em>ends the server</em> on 3.3a, taking every session on that socket with it —
including sessions this program never created. Every other supported release answers
{@code invalid layout} and carries on.

<p>A name that cannot be misspelled cannot trigger that. {@link Window#applyLayout} covers the
other way in, a serialized layout string, by checking it before tmux sees it.
