  1. The entire document should be self-explanatory.
  2. Avoid introducing irrelevant external content.
  3. Stay tightly focused on the topic.
• Opening Design: Write an introduction of about 200 words.

  2. Level-2 headings should be summarized in seven characters or fewer, without colons or bold symbols.
  3. Include a 50–100-word paragraph explaining the stage objective.
  4. If needed, display a technical decision tree diagram (using Mermaid syntax).
  5. If needed, showcase key command code blocks.
