Group of 2 Under the hood
Image resizing tracks a separate, stricter reject-size ceiling above the normal target width/height
What
Image resizing now computes rejectMaxWidth and rejectMaxHeight as the larger of the caller's configured bound and a new fixed value of 1568, via a new helper. These are added alongside the existing maxWidth/maxHeight target-size fields on the resize configuration, and did not exist before.
Why
This lets Claude Code reject images that exceed a hard size ceiling even when the normal resize target is smaller, tightening validation beyond simple resizing.
