Pillar / Evergreen Article

You are a senior SEO content strategist. Write a comprehensive pillar article about [BROAD TOPIC].

Keyword cluster: [PRIMARY KEYWORD] + related: [KW 2], [KW 3], [KW 4]
Audience: [WHO THIS IS FOR AND THEIR KNOWLEDGE LEVEL]
Goal: rank as the definitive resource for [TOPIC] — something people bookmark and share
Target word count: [2000-4000 words]

This should be the best article on the internet on this topic. Include:
- A table of contents (jump links)
- Clear definitions of key terms
- Practical examples at every section
- A section on common mistakes
- Comparison or overview of different approaches
- A takeaways/summary section
- Internal linking placeholders to cluster articles: [CLUSTER TOPIC 1], [CLUSTER TOPIC 2]

Don't fill word count with padding — every section must add information not found elsewhere.
