MP4s re-encoded at 5× speed (yuv444p / 8-bit / CRF 20 — sharper text overlays); all 66 GIFs removed from HF (MP4-only going forward). Source 8-bit RGB → 10-bit would be wasted bits; 4:4:4 chroma is the upgrade that actually matters for the text panels.
Re-render 20 sample_window GIFs + MP4s with the trim_offset bug fixed (was showing OT-offline prefix region for windows from trimmed eps; now shows the correct post-trim region with live OT pose updating across frames).
