libtmux::Server::load_buffer(name: std::string_view, from: const std::filesystem::path &) -> expected< void, CommandFailure >
```

Read a file into a named buffer, and write one back out.

The file is read and written by the tmux server, so the path is the server's to resolve — which matters when it is not on this machine. The bytes are not interpreted: a buffer round-tripped through a file comes back identical.
