@norbital-ai/ui/capture (§3.6): its own entry, so the face engine and weights load only in pages that import it.

CaptureKit component

component CaptureKit(props: CaptureKitProps)

A guided face capture: prompts through poses, holds each until the face engine sees it, optionally checks liveness and speaks the prompts, and reports each capture.
