 * Archive uses the default 3-column chrome grid (200 / 1fr / 260)

 * timeline, right sidebar (widgets). On narrow viewports the chrome
 * stacks; the .main-archive scroll behaviour is overridden below.
 *
 * The right sidebar collapses if empty: the dynamic_sidebar() call
 * emits nothing when no widgets are active, so the <aside> renders
 * empty and the :empty CSS hides the column entirely, restoring the
 * full width to the timeline.
