 ## Lazy arguments

+Any function passed **after** the first argument is invoked only if the event will actually be emitted (console and/or Sentry). That keeps expensive snapshots cheap when the level is suppressed.
 
 ```ts
-logger.debug("state", () => buildHugeSnapshot()); // skipped when debug is suppressed

-logger.debug("response", async () => ({ data: await res.json(), url }));

 ```
 
-Top-level thenables (including Promises returned from lazy factories, or a Promise passed directly as an argument) are settled before sinks run. The log call stays fire-and-forget (`void`). Settled events set `LogEvent.async`, and the console sink renders an `[async]` label suffix. Nested promises inside plain objects are not walked — compose them inside the async factory. Async emits may appear out of order relative to sync logs.
