Adds a transcript_comparison check to VideoCompose._run_final_review that word-diffs the whisper/whisperx transcript against script.txt and fails loudly when the TTS engine literally voiced punctuation tokens (dot, dots, ellipsis, comma, dash, hyphen, period). Chirp3-HD did this to ellipses in a production run and it slipped past review; now it cannot. Also corrects the "tiny background video" gotcha in skills/core/hyperframes.md. After six renders of blaming HyperFrames CSS, the real root cause was 640x360 Pexels sources combined with a fit-and-pad pre-transform — HyperFrames was rendering the letterboxed input faithfully. Gotcha now walks through the ffprobe diagnostic and the scale-to-cover fix, and keeps the wrapper-div pattern for the right reasons (aspect mismatch handling, not framework bug workaround). Four regression tests cover the new check: punctuation-leak detection, clean-audio false-positive guard, graceful skip when inputs missing, and always-present transcript_comparison section.
