+ * TextArea — multi-line text input с handoff tokens. Заменяет {@code @nstart/ui}
+ * TextArea (Phase 3 migration step).
+ *
+ * Поддерживает 2 режима (как Input):
+ *  - "bare" — просто <textarea>, для inline использования.
+ *  - "field" — когда задан label/hint/error, рендерится FormField обёртка.
