          skill). At md:col-span-5 the text column was only ~320px at
          768-1023px viewports, too narrow for the heading/CTA/social-proof
          row (which wrapped to 3 cramped lines). Staying stacked full-width
          through the whole Tablet range and only splitting into the 5/7
          grid once there's real room (≥1024px) fixes that without touching
          the 5/7 ratio itself, which is fine once it has space. */}

            ratio at 100vw would make the image ~600-900px tall and
            dominate the page, so height is capped and object-cover crops
            it into a supporting banner instead; at lg:+ (grid, image only
            58% width) the full aspect ratio looks right again, so the cap
            is lifted. A small negative top margin below lg: pulls it up to
            slightly tuck under the text block (deliberately less than the
            social-proof row's height, so it never covers the avatars/text).

            looked worse than no shadow at all — tried and reverted. */}
