  /* Bug fix (Phase 5a): 120px was one of three disagreeing, inaccurate
     hardcoded pixel offsets that caused the sticky-header "grey bar" bug
     (see Phase 3b Task 4's js/sticky-nav.js and css/base/reset.css
     changes). Previously coordinated via a temporary
     "#innerpage-nav.sticky" override in css/base/customizations.css,
     which this component's own CSS now replaces natively -- that
     override is removed in this same task. Consumes the same
     --sticky-header-height custom property js/sticky-nav.js already
     computes and sets on the root element on every scroll event; 120px
     is kept only as the pre-JS/no-JS fallback. */
