/* ============================================================
   Impact — its own visual system, not a reskin of any other page.
   No photo hero, no grid-texture backdrop, no ticker, no numbered
   card grid up top: a concentric-rings emblem instead (Access, Jobs,
   Emissions as nested layers), because this page has no real figures
   to show yet — the credibility here comes from the measurement
   process, not a stat strip with numbers we can't back up.
