   composites on purpose: no mix-blend-mode and no filter, because a blend mode
   here forces the whole tall .hero to rasterize as one isolated group, and iOS
   Safari tiles those and leaves a visible seam across the section.
   The mark is a corner ornament, not a row element: equal insets pin it to the
   hero's top-right corner, deliberately above and outside the copy so it stops
   competing with the h1. Earlier revisions tried to relate it to the "$ whoami"
   row — centred on it, then flush with its top edge — and both read as a large
