   Subject grounding: environmental survey & EIA work reads terrain through
   contour lines and elevation profiles. That motif (not a generic leaf/
   globe icon) is the visual signature carried through nav, dividers and
   footer. Typography pairs an editorial serif (reports, credibility) with
   a mono utility face (field data, reference codes, coordinates).
