 - This alias does not introduce a new runtime type or wrapper layer.
 - It preserves the same async lifecycle helpers as other async logger aliases.
 - Because this is only an alias, methods that are async on `AsyncLogger[@bitlogger.FormattedConsoleSink]` remain async here as well.
+- The alias therefore keeps the same text-console-specific builder and lifecycle semantics already documented on `AsyncLogger[@bitlogger.FormattedConsoleSink]`, including the concrete sink shape and runtime-dependent close/failure behavior.
 - The alias exists to give application code a clearer public name when it wants the concrete text-console sink shape explicitly.
 - `build_application_text_async_logger(...)` returns this alias.
