Backend: send border_width in WS metadata and frame_dims (width, height) as a separate JSON message on first JPEG frame. Frontend: render semi-transparent green overlay rectangles on each active edge showing the sampling region depth, plus a small px label. Overlays are proportionally sized based on border_width relative to frame dimensions. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
