 * The look of a name drawn on the sky (the property `skyStyle` of `<chikyu-space>` and `<chikyu-earth-realistic>` takes any part of it): font, size, weight, colour, outline, case, letter spacing, the leader line, the ring round a star and the catalogue letter under the name. These are
 * hoshi-stars' `LabelStyle`, with the same defaults and ranges, written out so a page without hoshi-stars installed still type-checks.

 * @example
 * ```ts
 * import type { SkyLabelStyle } from "@johnmorrisdotca/chikyu-earth/realistic";
 *
 * const look: Partial<SkyLabelStyle> = { size: 12, colour: "#ffe9b0", case: "as-written", ring: 0 };
 * console.log(Object.keys(look).join(" "));
