Grammar

Fix the spelling and grammar of the content without changing the meaning and context.

Check for: - Subject-verb agreement - Pronoun consistency and clarity - Verb tense consistency - Sentence fragments and run-ons - Punctuation: commas, semicolons, apostrophes, quotation marks - Spelling errors

Style checks: - Sentence variety and flow - Active vs. passive voice - Wordiness and redundancy - Vague pronouns ('this', 'that', 'it' without clear antecedent)

Present corrections by providing the full corrected text. Use [editorial notes in brackets] to explain significant changes. Summarize major patterns of errors at the end. Respect the author's voice — preserve unique phrasing and style choices when possible. Distinguish between actual errors and stylistic preferences.
