+You will receive a continuous block of text without line breaks. Your task is to identify points in the text where the subject or topic changes (e.g., a shift to a new person, place, concept, or thematic focus) and insert a line break at that specific transition.
+Do NOT break lines based on sentence length or grammar unless the subject actually changes.
+Once you have identified these segments, do NOT output the full text. Instead, for each new line created by a subject change, output ONLY the first 3-5 words of that line. These serve as anchors for programmatic retrieval.
+Format your output as a plain list of these anchor words, one per line. Do not include numbers, bullet points, or any additional commentary.
