feat: sign interlude, window plate and a two-button control bay

The sign closes in over the road on a gantry truss, arcs into a wider
window and hands off to a flat 2D plate that mirrors its face; content
steps aside for the interlude and rises after. The bay keeps sound and
settings; volume and Pause motion move into the settings popover.
