/* hero visual — a stylized "clip" card */
/* Hero card. Shows a REAL generated clip and a real question from the bank, injected by
   tools/build_site.py. The previous version faked a traffic scene with coloured divs
   (.road/.dash/.car/.cyc, now removed) — a mock-up of the one thing we can actually
   render at volume. The answer is deliberately not revealed here.

   aspect-ratio must match the renderer's native 1280x600, same as the app's .stimulus.
   Using 16/9 here made the card a quarter taller than it needed to be AND cropped ~17%
   off the sides — on a hazard clip, where the thing being tested is often near the edge. */
