/* ================================================================= *
 *  Narrow and short windows
 *
 *  The zoom and page readouts belong in the bottom-right corner - that is
 *  where people reach for them, and moving them is more disruptive than the
 *  overlap they were moved to avoid.
 *
 *  The toolbar is a centred row about 825px wide; the readouts are about
 *  230px. Centred against right-anchored, they start to collide at roughly
 *  1310px. So instead of lifting the readouts, the toolbar stops centring on
 *  the window and centres on the space to the LEFT of them. It shifts a
 *  little left of true centre, and it never reaches the corner.
 *
 *  Only when the window is too narrow for even that (under 860px on fine
 *  pointer, or on touch tablets) does the toolbar take the full width and the
 *  readouts step up out of its way.
