-    Normalize prompt text to prevent tokenization errors.
-    
-    Converts None, empty strings, or whitespace-only strings to a single space.
-    Ensures the input is a string type by converting non-string values.
-    This function is designed to handle edge cases gracefully without crashing,
-    which is important for ComfyUI workflows where users might have empty prompts.
-    
-    Parameters:
-        text: The input prompt text to normalize. Can be of any type, though
-              string, None, or convertible types are expected.
-    
-    Returns:
-        str: A normalized string that is safe to pass to the tokenizer.
-             Returns " " (single space) for None, empty, or whitespace-only inputs.
-             Returns the original text unchanged if it's a valid non-empty string.
-             Returns str(text) for non-string types.
