/* Gotthard Stau — design system (2026-07 redesign).

 * direction = categorical slots 1+2, heat = fixed status scale) plus ONE new
 * semantic hue: --forecast (#199e70, validated against BOTH direction colors
 * in BOTH modes, no contrast relief needed). Semantics everywhere:
 *   gemessen  = direction color, solid line
 *   Prognose  = teal, dashed line + teal wash band
 * Direction colors never encode measured-vs-forecast again.
