   HANI ABBAS — PORTFOLIO
   Design concept: "Blueprint to Canvas"
   The engineer's grid meets the artist's brush — structure on
   the left brain, expression on the right. Ink navy + blueprint
   line-work grounds the site; brass gold marks every place
   craft/creativity breaks through the grid.
