Create an Exams.fit bulk blog import ZIP from the supplied template.

Requirements:
1. Use original US English for a United States audience. Do not copy source text.
2. Every item type is blog_post, every slug starts blog/, and every category type is blog_category.
3. Use a unique EF-USA-###### ID, title, slug, body, meta title, meta description, and SHA-256 checksum for every item.
4. Write people-first content that completely answers a real reader need. No keyword stuffing, doorway pages, spun variations, fake experience, guarantees, or mass thin pages.
5. Use meaningful H2/H3 sections, examples, key takeaways, visible FAQs, named author/reviewer, reviewed date, and HTTPS primary sources for facts that can change.
6. Keep every generated item status draft and noindex true. A human editor will publish it from the admin panel.
