   DIRECTION A · "STRUCTURE"   →  revamp1.mesaquantum.com
   Provenance: the route Wale chose in the June discovery survey —
   "Route C — Typography & Structure Led". Also the closest reading of
   the Lockheed Martin anchor: a clear message, disciplined grid,
   imagery that depicts rather than decorates.
   Character: light, editorial, high contrast. Type carries the page.
   Primary motif: the logo OUTLINE (the formal register of the toolkit).
