An inline note in the page flow: a tip, a heads-up or a result to act on. A raised surface with a 16px icon, a title, a line of detail, and an optional action and close button. Only the icon takes the status color, and a hidden word before the title says the same thing, so there is never a rail, a tinted fill or a colored border. It measures its own width and drops the action below the text under 28rem.
