   Julian Köttstorfer — Portfolio
   Hero section

   Direction: an engineer's field instrument — dark khaki "canvas",
   a faint blueprint grid, a live particle/node network, and a
   monospace spec-sheet of real facts. Precision over decoration.

   Type roles:
     display  → Space Grotesk   (name, section labels)
     body     → Inter           (title, tagline, buttons)
     utility  → JetBrains Mono  (eyebrow, meta spec-sheet, scroll cue)
