   #hero-overlay uses two pseudo-elements layered on top of each
   other rather than one gradient, because the legibility problem
   has two different shapes:
     ::before — horizontal left-to-right fade, dark on the left where
                the headline sits, fading to transparent on the right
                where the video itself is the visual interest
     ::after  — vertical top/bottom vignette, keeping the nav bar and
                CTA buttons readable regardless of what's playing
                behind them at that moment
   Both layers get re-tuned per breakpoint further down — see the
   responsive section near the bottom of this file for the tablet/
   mobile/small-mobile variants of each. ──────────────────────── */

     768px  → standard mobile
     480px  → small phones

   Mobile menu styling lives inline within this section (see the
