+ * version-picker.js — LootLocker Unreal SDK
+ *
+ * Replaces the static #ll-topnav-version span with a <select> dropdown
+ * that lets users navigate between published doc versions.
+ *
+ * The list of available versions is fetched from versions.json at the root
+ * of the published site (one level above the current version directory).
+ * Falls back gracefully to the static badge when versions.json is unavailable
+ * (e.g. local Doxygen builds).
+ *
+ * Expected versions.json shape:
+ *   [
+ *     { "version": "latest", "path": "latest/" },
+ *     { "version": "v2.5.0", "path": "v2.5.0/" }
+ *   ]
+ *
+ * URL resolution:
+ *   The script detects the current version directory by looking at the last
+ *   path segment of the page URL and resolves versions.json relative to the
+ *   site root (two levels up from the current page, one for the HTML file
+ *   and one for the version directory).
