  /* skarpvect-primary.svg's viewBox (0 -2.56 778.97 128.21) is a tight crop
     of the ink — no padding baked in. Its own geometric centre (y=61.54 in
     that coordinate space) is NOT where the wordmark optically balances,
     because the "p" descender in "vect" reaches ~76 units below the S while
     the tallest ascender only reaches ~53 units above it — a symmetric crop
     around that centre would add a dead zone above the letters to match the
     descender's reach below, which is what made earlier passes at this
     still read as bottom-heavy. Instead crop tight and nudge the rendered
     logo down by the gap between the box centre and the S glyph's own
     optical centre (y=50.0), so flex-centering the header aligns the S —
     not the box, not the descender-inclusive bbox — with the row's midline.
     11.54 / 128.21 = box centre (61.54) minus S centre (50.0), as a
     fraction of the tight-crop viewBox height. */
