 * the layout pushes back when it grows: whatever the pane takes comes
 * straight out of the content column. Without a clamp against the space
 * actually available, shrinking the window (or expanding the sidebar)
 * leaves the content column a few dozen pixels wide instead of folding.
 *
 * The host application's sidebar width is a parameter rather than an
 * import, so the policy carries no coupling to any particular shell.
