/* Gotthard Stau — quiet alpine dashboard.
 *
 * Design tokens follow the dataviz skill's validated reference palette:
 * direction colors are categorical slots 1+2 (north blue / south orange —
 * colorblind-safe, validated in both modes), heat levels use the fixed
 * status scale (always paired with a text label, never color alone).
 * Dark mode restates the same hues stepped for the dark surface. */
