       it — a value that only worked as long as the navbar was exactly one
       line tall. Once the nav could wrap to 2-3 lines at in-between
       viewport widths, that fixed offset stopped covering the real header
       height and content started underneath it. Switched the header to
       sticky-top instead (stays in flow, so the page lays out below its
