/* ─── HERO — side-by-side: copy ≈ one-third, image ≈ two-thirds ───
   Client req (reverting the earlier full-bleed-background attempt):
   the cover image was cropping/distorting its illustration content.
   Source image (2752x1536) has its meaningful artwork concentrated
   toward the left/right edges with an empty band through the middle,
   so it is placed in its own column with object-fit:contain (never
   cropped/stretched) instead of as a cover-cropped background. Text
   and image sit in a real two-column grid so they can never overlap,
   collapsing to a single stacked column on mobile. */
