Facebook Page Humanizer V3

Rewrites any Facebook Page post to remove the AI tells that human readers notice, and audits a finished draft against the 2026 Facebook ranking checklist. Based on Wikipedia's "Signs of AI writing" taxonomy, the 2025-2026 stylometry literature, and Facebook-Page-specific patterns (the under-80 sweet spot, the "See more" fold, the "We are thrilled to announce" corporate tell, and the meaningful-interactions model). V3 (2026-09): recalibrated on 2026 evidence. Vocabulary is scored by density, em dashes are capped instead of banned, forced rhythm is now a tell instead of a fix, and there is an over-correction guard. Facebook has no corpus of its own yet, so the calibration follows the LinkedIn one (the closest long-and-short mixed feed).
