/* ==========================================================================
   ferto.de — revamp preview (/new)
   SELF-CONTAINED. This file does not depend on /style.css and must never be
   loaded alongside it. The live site keeps /style.css untouched.

   Direction — "the optical bench record".
   The page is RULED, not BOXED. A microscope's world is a ruled one: the
   graticule in the eyepiece, the grid of a counting chamber, the margin of a
   lab notebook. So structure is carried by hairlines, hanging labels and
   uneven whitespace — enclosure is reserved for the two things that have
   earned it. Two voices: Inter for the human, mono for the instrument.
   Signature: focus-reticle corner ticks, lifted from the product's own
   annotated-cell overlay, used on the three statement lines and nowhere else.

   Scrim — the credentials must be read, not decoded.
   These three lines are the only proof points above the fold, and they
   sat directly on the animated NET field: lines and dots ran straight
   through the text and the hairlines. A contrast ratio against a moving
   backdrop is meaningless, so this gives the text a KNOWN one.

   It is anchored to the strip, not to the hero's foot: the block is
   vertically centred, so on a tall viewport the strip sits ~490px above
   the hero bottom and a bottom-anchored scrim would flood 400px of empty
   hero. This fades in above the strip, is FULLY OPAQUE --tint across it,
   and fades back out below — so the animation stays prominent where the
   headline lives and re-emerges underneath.

   Geometry (px offsets, so it holds at any strip height):
     top: -184  ->  solid begins at 160px = 24px ABOVE the top rule
     bottom: -160 -> solid ends 120px before the foot = 40px BELOW the strip
   Clipped by .hero{overflow:hidden}, so 100vw cannot cause page scroll.

   The two shots have different native ratios (bench 864/1080 = 0.8000,
   phone screen 923/1325 = 0.6966). Rather than crop either one, the COLUMNS
   are sized 0.8000/0.6966 = 1.148 apart, so both images render at exactly the
   same height with nothing cut off. Column gap does not disturb this — fr
   distributes the *remaining* space, so the 1.148:1 ratio is preserved.
   If you swap an image, recompute the two fr values — don't add aspect-ratio
   or object-fit here.

   The fr pair is each image's aspect ratio cross-multiplied, so it is exact
   rather than rounded:  864x1325 = 1144800  and  923x1080 = 996840,
