/**
 * Svelte hook that picks one dictionary by its key and returns its reactive content.
 *
 * It returns a readable store that reactively updates whenever the locale changes.
 *
 * The second argument is either a locale or a selector object:
 * - `{ item: 2 }` — collection item (omit `item` to get every item as array)
 * - `{ variant: 'black-friday' }` — named variant (omit for the `default` one)
 * - `locale` composes with any selector and overrides the context locale
 *
 * @param key - The unique key of the dictionary to retrieve.
 * @param localeOrSelector - Optional locale or selector.
 * @returns A readable store with the transformed dictionary content.
 *
 * @example
 * ```svelte
 * <script>
 *   import { useIntlayer } from 'svelte-intlayer';
 *   const content = useIntlayer('my-dictionary-key');
 *   const faq2 = useIntlayer('faq', { item: 2 });
 * </script>
 *
 * <div>{$content.myField.value}</div>
 * ```
