Refining for word count and tone:
The current draft is too short (approx 70 words). I need to expand while staying strictly within the facts. However, the sources are very sparse. I cannot invent details. I must use the provided facts to reach the word count target or acknowledge the limit of the provided information. Wait, the instructions say "Write a 180-260 word career overview". If the sources don't provide enough info to reach 180 words without inventing facts, I have a conflict.
