+/**
+ * Ambient declarations for JavaScript globals provided natively by the
+ * iOS and Android runtimes (ada-url based, see the runtime URLImpl and
+ * URLSearchParamsImpl sources), so they resolve in projects compiled
+ * without the DOM lib.
+ *
+ * Follows the approach @types/node uses for web globals
+ * (types/node/web-globals/url.d.ts): the shapes are declared at module
+ * scope and bound inside `declare global`, so the global interfaces merge
+ * with — and the `var` declarations adopt the type of — any existing
+ * global definitions of URL/URLSearchParams (e.g. from lib.dom) instead
+ * of conflicting with them.
+ *
+ * Members that the runtimes do not implement (URL#toJSON, URL.parse,
+ * webkitURL, ...) are omitted; the URL constructor requires a string
+ * first argument because the runtimes throw a TypeError for anything
+ * else.
