/* HashBench site — shared design tokens and components.
 *
 * Chrome keeps the reference-price design language (IBM Plex, Archivo Narrow
 * labels, teal accent). Data series use a validated categorical palette
 * (blue, orange, aqua: all-pairs CVD-safe in both modes on these surfaces),
 * status uses reserved colors that never stand for a series, and every status
 * ships with an icon and a label.
