We need to write an original article for keyword "Rosa Parks Coloring Book". Use given context when useful. Must be 600-900 words, natural headings, use only safe HTML tags: h2, h3, p, ul, ol, li, strong, em. No markdown fences. No mention that AI-generated. Provide SEO-friendly article.

(maybe not relevant but can be included as link but we cannot use a tag? Actually we can include raw URL? It says do not include markdown fences. But we can include plain URL. But we must not use anchor tags because not allowed. So just include the URL as plain text. Also include "https://chrisbeaven.com/drawing/". Use these contexts when useful.

Rosa Parks Coloring Book: A Creative Way to Celebrate History

...

Include context: "Celebrate the legacy of". Use "Celebrate the legacy of Rosa Parks with a coloring book that brings her story to life." etc. Also "Bring the legacy of" etc. Also "This free" maybe we can say "This free printable version includes..." but need to be careful not to claim it's free if not true? It says "This free" twice in context. Could be "This free resource" etc. We can say "This free downloadable PDF" but we need to avoid unsupported claims. Might just say "This free option" as a phrase but not claim it's actually free unless we have evidence. Safer to just use the phrase as part of context but not assert it's free. Could say "This free" as part of a sentence: "This free resource can be shared with teachers and parents." That might be okay but might be unsupported claim. Better to keep it generic: "This free" maybe we can embed it as part of a sentence but not claim it's free. Could just include the phrase "This free" as part of a sentence but not claim anything. Eg: "This free coloring page can be printed at home." That's a claim about being free; might be unsupported. Safer to avoid claiming it's free. But the instruction says "Use this context when useful". So we can include the phrase "This free" as part of text, but we must not make unsupported claims. So we can say "This free" as a phrase but not claim it's free. Eg: "This free" could be part of a larger phrase: "This free coloring page is available for download." That's a claim. Might be okay
