   VASTUDNYA DESIGN — Design System
   Concept: "Working Drawing" — the site is styled as a set of architectural
   / structural working drawings: drafting paper, blueprint ink, dimension
   lines, tick marks, sheet numbers and an engineer's stamp. Numbered
   grid labels (A/B/C, 1/2/3) are used because they mirror real drawing
   grid references, not as decoration.
