   VOSSEN — Architectural Blueprint Design System
   Design system for an architecture / interior design studio.

   Thesis: "An architectural blueprint — precision lines,
   measured spaces, material palette. Every section reads
   like a drawing sheet with annotations, the hero is a
   facade elevation, and the projects are material boards."

   Materials: concrete, glass, steel, wood grain
   Motion:    elevation slide / grid fade / material reveal
   Grammar:   blueprint sheet — grid lines, annotations, specs
