   Responsive
   The mockups are a fixed 1440px; everything below was built here.

   Two breakpoints, for two different reasons:

     1240px — the two-column rows give up. The hero's portrait (516px) and the
              results card (410px) are fixed widths, so the text column beside
              them absorbs every pixel lost. Measured: at 1140px it is down to
              418px, which wraps the hero heading to four lines and breaks the
              button label across two. Below ~880px it overflowed outright.
              1240px is where the text column still clears 500px.

      760px — phone. Type scales down through :root, gutters tighten, rows and
              buttons go full width, and every tap target clears 44px.
