Local processing inputs

Local Worker: 10s startup, 1s processing. 32KiB per field, 1MiB complete result. Editing or clearing cancels work and stale output. Generated HTML/CSS is not mounted; remote image preview requires a separate action.

Preview and code

Edit fields and build a preview; complete code can be copied or downloaded.

Model and scope

Generate a monotonic two-stop alpha mask. Linear directions use angle units or top/bottom/left/right keywords; radial uses a centered circle. Stops must be ordered within0–100%. Preview masks a generated local illustration; no image is fetched.
