Principles that point forward

1
Direction over decoration
Every element earns its place on the board. We remove what doesn't advance the argument.
2
Legibility at every scale

3
Depth without noise
Four blues, one white. Hierarchy built through restraint, not volume.
4
Systems that outlast trends
Vector Sans was drawn for an airport brief. It reads sharper today than the day it was cut.
