defmodule Mob.Clipboard do
@moduledoc """
System clipboard access. No permission required.
## Write
def handle_event("copy", _params, socket) do
Mob.Clipboard.put(socket, socket.assigns.text)
{:noreply, socket}

## Read

`get/1` dispatches to the main thread synchronously (same model as
`safe_area/0`) — fast enough to call from any callback.
"""
@doc """
Write `text` to the system clipboard. Fire-and-forget; returns the socket.
