/* HERO IMAGE — fixed 5:4 frame. Do NOT go back to `height: 100%` with the grid
   stretching this column: the tricycle photo is 16:9 but the vehicle only spans
   the middle 57.5% of its width (measured: x 20.6%..78.1%). With object-fit:
   cover, the visible window is (container aspect) x (image height) px wide,
   while the vehicle itself is always 57.5% x 16/9 = 1.022 x the image height
   wide. So any container narrower than ~1.02 aspect MUST slice the cargo box,
   no matter how the source is cropped (horizontal cropping cancels out of the
   inequality — only the height ratio matters).
   Previously the column was stretched to the text height, so the container
   aspect was driven by copy length: English text is taller than Chinese, the
   English container fell to ~0.98 (near square), and ~44% of the width got
   cropped away, cutting the windshield and the cargo box. Chinese (aspect
   ~1.18) stayed above the threshold and looked fine.
   A fixed 5:4 frame keeps the window at ~1.25 aspect on every language and
   every viewport, so the whole vehicle stays ~46px clear of both edges. */
