/* Meridian analyst workbench.
 *
 * LIGHT IS THE DEFAULT. The dark palette is opt-in via the rail toggle, which
 * persists to localStorage. `prefers-color-scheme` is deliberately NOT used to
 * pick the initial theme: the requirement is light by default regardless of OS
 * setting, and silently following the OS would contradict that.
 *
 * Evidence colours are the only saturated hues in the interface, and they are
 * tuned separately per theme so a modeled estimate stays visibly distinct from a
 * measurement at both light and dark contrast ratios. That distinction is the
 * product, not decoration.
