CopyTextBox

A Mosaic styled text box with an attached copy button that places the box's text onto the clipboard. The button shares the text box's border (drawing only its left edge) so the two read as a single control, clipboard failures are handled rather than thrown, and an optional toast notification can report whether the copy succeeded.
