   FOOTER — misty fjord sign-off
   The stage keeps the sky photo's native aspect ratio (5472×3040) so every
   layer can be placed in % coordinates and stay glued to the photo at any
   viewport width. Depth sandwich, bottom to top:
     photo (sky+scene) → white blend into the section above → MARINE
     wordmark in the sky → mountain cutout (transparent sky, 5472×1985,
     bottom-anchored = bottom 65.3% of the stage) overlapping the letter
     bottoms → INSPECTION AI + tagline → legal → link columns.
