   `is-shown` puts it on the page, `is-open` slides it into place. Opened by a
   click it is shown first and then opened, so it slides in from the right;
   closed, it slides out and is hidden once the slide has run. A history step
   (Back, Forward) or a page loaded with the panel's address sets both at once,
   in the same frame as the route: no slide, and never a frame with the panel
   in its old state. On narrow screens it moves a short way, not its whole
   width, fading as it comes — as the site menu and the article info drawer
   do; on wide screens its whole width, the fade on its own ease. The host
   column clips the panel horizontally (see article/article-view.snippet.css),
   so no scrollbar flashes while it slides. When switching authors the two
   panels overlap in one grid cell: the open one is above the leaving one. */
