/* Covers common "smaller laptop" widths (~1200-1460px logical). Below full
   desktop width but above the 900px tablet breakpoint, the 8 nav items at
   full gap/font-size don't fit on one line — the longest item ("The
   Challenge") wraps to two lines, which grows the fixed-height nav bar and
   makes it overlap the hero content beneath it. Shrinking gap/font/padding
   here keeps everything on a single line without engaging the more
   aggressive scroll/compact treatment below. Threshold verified against the
   live site: nav wraps up to 1445px logical width at full size, confirmed
   clean at 1450px+; 1460px sets this breakpoint with a small safety margin. */
