Both [TextHandler] and [JSONHandler] can be configured with [HandlerOptions].
There are options for setting the minimum level (see Levels, below),
displaying the source file and line of the log call, and
modifying attributes before they are logged.

Setting a logger as the default with

	slog.SetDefault(logger)

will cause the top-level functions like [Info] to use it.

	// If present, this field configures columns for all versions.
	// Top-level and per-version columns are mutually exclusive.
	// If no top-level or per-version columns are specified, a single column displaying the age of the custom resource is used.
