Selecting a link only brightened that one hop's edge; the path that reaches it
read no differently from the rest of the fan. Draw the route to the selection —
its own edge plus the approach the walk took into the focus (came_from → focus)
— at top priority and full strength, shedding the evidence-age fade the other
edges keep, so it reads as one lit thread running west through the focus to the
selected neighbour east. The age stays legible in the row's age column.
