 - A way down the tree from every page: an arrow fixed at the left edge, half-way up, and the same link in words at the foot ("Tilbake til starten", "Back to “What came in?”"). It goes to the nearest page below the current one that the visitor may open, taking the path apart a segment at a time, and to the front door when none is; the front door has none. Content no longer needs a "back" alternative, and a visitor who went up a branch that turned out not to apply is never stranded.
