   10. HERO
   Image-only, no overlay text/buttons — the photo already carries the
   wordmark card and tagline.

   Mobile (<768px): the illustration is wide (~1.78:1). Cropping it to
   fill the viewport height cut off the bus and/or the wordmark card, so
   below 768px the hero instead follows the image's natural aspect ratio
   — the whole illustration renders uncropped, sitting under the sticky
   header, and the page simply continues into the next section below it.

   Tablet/desktop (>=768px): reverts to the full-bleed viewport-height
   cover crop, tuned per breakpoint, which has room to frame both the
   bus and the card without cropping either.
