7// embedded, and a mark when something failed. Hovered or focused, it opens a card: its name, how far
8// its reading and embedding are, in words and as a bar, what failed, and its refresh. Companies are
9// everyone's, so there is no stop and no delete. The card is placed against the window, so the
10// scrolling list does not clip it. One card is open at a time: hovering another chip swaps it at once.
