keeps: bump oven thumbnail quality + duration to keep objkt's animation path
objkt's asset CDN flattens low-entropy animated WebPs to static JPEG in its
thumb288 render (happened to $pie: 41KB / 32 frames = 1.3KB/frame → JPEG).
Sibling token $sum at 268KB / 40 frames = 6.7KB/frame was kept as animated
GIF. Bump oven params (quality 70→88, duration 4000/5000→6000/7000, fps 8→10)
so per-frame bytes clear whatever their heuristic threshold is.
