 * {@link ActivityBar} bound to the pane store for one edge.
 *
 * Derives its items from the panels registered on that edge and toggles the
 * open one — clicking the already-open item closes the pane. Items with
 * `align: 'end'` go to the far group, which is how settings ends up at the
 * bottom without the rail knowing what settings is.
 *
 * Renders nothing when no panels are registered for the edge. An empty rail is
 * a twelve-pixel strip of nothing, and both edges behave the same way — the
 * left rail used to render regardless, which made the two sides subtly
 * different for no reason anyone had chosen.
 *
 * There is no bottom rail: a bottom drawer is toggled from the status bar, a
 * command or a keybinding, and a horizontal strip of icons under the workspace
 * costs more room than it earns.
