One origin asset, any delivery shape. Pixelforge reads the transformation out of the request path, renders the derivative in memory, and streams it back with long-lived cache headers. No build step, no pre-generated variant folders to keep in sync.
Derivatives are keyed by their full path, so every distinct size, crop and format is cached independently once it has been requested a single time. Unused combinations cost nothing, and clearing a source clears all of its derivatives with it.
