Cool, precise diagrammatic flat illustration with clean geometric shapes and thin ruled lines, like an architectural drawing of a glass office tower at dusk with a few lit windows, a long downward-sloping road in the foreground, limited palette of near-black ink and cobalt blue on plain white (the only colour besides black is cobalt blue), bold simple silhouettes, generous empty space, magazine infographic style, no text, no letters, no numbers, no border
