   column width — it paints straight past the column edge into the next one,
   which the .nav-col fix above cannot prevent (overflow: visible does not
   enlarge the parent's own box, so nothing here reads as "overlapping" to a
   bounding-box check — only to the eye). Three classes beats main.css's two
