/* ================================================================
   GeoSift — Landing page (marketing surface)
   Dark mode only · Matches index.html / styles.css aesthetic 1:1

   Ambiguity calls made (autonomous):
   - Hero product peek = framed iframe of index.html (renders the
     real mockup; reads as "live" without static-screenshot drift).
     Field section uses an iframe of mobile.html in a phone frame.
   - Vertical packs section = 4x3 responsive grid (not a horizontal
     scroller). Cleaner desktop reading; reflows to single column.
   - Engine + Verticals diagram = stacked-card stack above an Engine
     "slab" listing the 12 P0 capability buckets. Reads as one
     foundation, many surfaces, without iso-3D complexity.
   - "Marketing/Ad" pack rendered as "Marketing / Ad" for legibility.
   - The hero "EARLY ACCESS" pill in the brand sits next to the
     wordmark to telegraph the page's purpose at a glance.
