/**
 * "Nord Dark" — the dark variant of the Nord palette (Arctic Ice Studio): muted
 * Frost/Aurora accents on the deep "Polar Night" `#2e3440` ground. Cool and
 * deliberately low-contrast. Pairs with `Nord`.
 *
 * This is a standalone theme; it does not modify any built-in theme.
 *
 * @see {@link https://www.nordtheme.com/} for the original palette
 * @see {@link https://www.amcharts.com/docs/v5/concepts/themes/} for more info
