 * with the bundled defaults. The toolbar only asks for the result; it does not know how a font previews.
 *
 * - A consumer-provided `configFonts` list is returned UNCHANGED (custom toolbars own their list).
 * - With no document options, returns `undefined` so the caller keeps its fallback to {@link TOOLBAR_FONTS}.
 * - Otherwise: bundled defaults and document fonts are deduped by normalized logical family, then sorted
 *   alphabetically by the visible font name. `label`/`key` stay the pure logical family (active-state
 *   matching + the stored value), and the preview renders in `previewFamily`.
 *
 * @param {ReadonlyArray<import('../../../../../shared/font-system/src/index.js').DocumentFontOption>} documentOptions
 * @param {Array} [configFonts] - the consumer's `fonts` config, if any
