(https://lucide.dev), icons `circle`, `square`, `link` and `message-square`.

Contributors. The `circle`, `square` and `link` icons are derived from the

2013-present Cole Bemis. Both licenses permit use, modification and
redistribution provided their copyright and permission notices are kept; the
full texts are at https://github.com/lucide-icons/lucide/blob/main/LICENSE.
