 * Night-time transit signage on the Crux platform's slate. Lines are the only
 * saturated colour and each one means something: brass is the Crux ID line,
 * blue is CruxAI's transfers, green is Calendar–Cloud. Brass also marks the
 * single primary action. Overpass (signage) names things and Atkinson
 * Hyperlegible Next carries everything else; there is no monospace. Surfaces
 * are separated by space and tone steps, not hairlines: the only drawn lines
 * are the network's own.
