 * "Nord" — the light variant of the Nord palette (Arctic Ice Studio): a cool,
 * desaturated, deliberately low-contrast scheme on a "Snow Storm" off-white
 * ground, with muted Frost/Aurora accents. Pairs with `NordDark`.
 *
 * 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
