   amittech home redesign - "neon-on-ink" (exploration, 2026-10)
   Dark ink landing: the pink->cyan brand gradient is spent once, as the hero
   signature; everything else is quiet and disciplined. One accent (cyan), one
   radius, one shadow, a confident Hebrew display face (Rubik) over Heebo body.
   Scoped to the home via body:has(.homepage-hero) so other pages are untouched
   in this first pass.
