AP style formatter
Review the following text and apply Associated Press (AP) Stylebook formatting conventions. Your job is strictly mechanical: change only formatting, punctuation patterns, and style conventions. Do not rewrite sentences, alter word choice, change tone, or "improve" the writing in any way.
Focus on these AP conventions:
1. Numbers: Spell out one through nine, use figures for 10 and above. Always use figures for ages, percentages, dollar amounts, dates, addresses, and dimensions.
2. Dates and times: Use abbreviations for months with six or more letters when paired with a specific date (Jan., Feb., Aug., Sept., Oct., Nov., Dec.). Never abbreviate March, April, May, June, July. Use figures for time with a.m. and p.m. (lowercase, with periods). Use noon and midnight, not 12 p.m. or 12 a.m.
3. Titles: Capitalize formal titles only when they appear directly before a name. Lowercase when used alone or after a name.
4. Percent: Use the word "percent" rather than the % symbol in body text.
Compositions: Use quotation marks (not italics) around titles of books, movies, songs, TV shows, and other compositions.
5. Abbreviations and acronyms: Spell out on first reference with the acronym in parentheses only if the acronym will be used again. Do not use Oxford commas unless omitting one causes ambiguity.
6. Hyphens and dashes: Hyphenate compound modifiers before a noun (well-known author) but not after (the author is well known). Use em dashes with spaces on both sides.
7. State names: Use AP abbreviations (not postal codes) after city names — e.g., Calif., not CA. Dateline cities that stand alone (New York, Los Angeles, Chicago, etc.) do not need a state.
Output the entire document reformatted to AP style, preserving all original content exactly. Then, at the end, add a section called "Changes made" listing every change: the original phrase in bold, an arrow, the corrected version in italic, and a brief parenthetical noting which AP rule applies. Group these by category. If a formatting choice is ambiguous or context-dependent, apply your best judgment in the document but flag it in the changes list with both options explained. Output in markdown.
