   pseudo-element above (same selector shape) — the reset properties just
   added (border/margin-left/vertical-align/display) neutralize Bootstrap's
   built-in caret shape without disabling the underline effect. The visible
   caret is a plain CSS border-triangle (not an <svg>) — mainMenu.html is
   fetched as a fragment and injected via innerHTML, and some dev servers
   (e.g. Live Server) auto-inject their reload script into any response
   containing an <svg> tag assuming it's an SVG file, which corrupts the
   fragment; a border-triangle sidesteps that entirely. */
