   Fix: the page is RTL, so the hero text sits
   on the RIGHT side of the grid — but the dark
   gradient was written left-to-right (90deg),
   putting the darkest shading over the empty
   left side and the lightest, most transparent
   part directly behind the headline and
   paragraph. Against a bright, busy photo that
   left the text almost unreadable. Flipping the
   angle puts the dark shading behind the text
   instead, and the box behind the text is
   darkened too as a second safety net.

   on top of the accreditation card / hero text
