/*
 * The page's tokens, both modes, from the org's validated palette.
 *
 * Dark is the default because this is a map and the moving marks are the
 * data; light is a selected set of steps from the same ramps rather than an
 * automatic flip. The two categorical hues — blue for vehicles, orange for
 * pedestrians — were validated as a pair against both surfaces (all-pairs
 * CVD ΔE 26.8 dark, 24.7 light, both far above the 8 target), and shape
 * carries the same distinction so identity is never colour alone.
 *
 * The canvas reads these same custom properties at draw time, so there is
 * one palette in the page and not two.
