Each concept is a complete six-page site running on real content, the real logo set, and one colour system derived from the New York photograph. They are not four skins on one layout. Every structural choice, the type pairing, the ground, the role of imagery, is deliberately different so the comparison is real.
Eleven delivery geographies. 4.2 million employment records. Every cost model in circulation assumes a convergence rate the data does not support.
Thirty years of workforce analysis was written by people with a position in the outcome.
Every dominant colour in the New York image sits between hue 206 and 213, at 14.8% mean saturation. Its median hue is 209, whose exact complement is 29. The logo’s orange sampled at #FDA333, hue 33. Within four degrees. The palette built itself.
Amber on white measures 2.01:1, a WCAG failure. So amber never carries body text on a light ground anywhere in these concepts. On ink it measures 8.63:1 and passes, which is why Concept 04 can use it structurally.
There is a single source image. It appears as a desaturated band, three distinct editorial thumbnails at 280/190/130% zoom, four hero grounds at different anchors, and a greyscale portrait strip.
