   Reworked into a full-bleed dark navy-gradient band for the Phase
   11 design-consistency pass, echoing the reference site's bold,
   dark, full-bleed hero (there, a photo with a dark overlay; here,
   the same navy/orange brand gradient used elsewhere on the page,
   since no licensed photograph is available to reproduce). Copy,
   links, and the existing abstract SVG graphic are unchanged — only
