Concepts
The engine runs bounded raster transforms inside the ocd process. Sessions have a TTL and a concurrency cap. Output is not automatically stored in Workers Cache; cache it explicitly with the Cache API if you need that.
Input formats for info are jpeg / png / webp. Output is jpeg / png / webp / avif. max_frames = 1: no animation.
