Render only the upper folding bridge-mast body for a premium Go-playing robot on a pure white studio background. Do NOT add any round pedestal, floor stand, docking puck, separate base plate, or support foot. This is just the mast body that would attach directly into the product's rear-right service spine.

The mast is a slim deep warm-gray (#6B6460) rounded rectangular pillar with a short hinge barrel segment at the very bottom edge only, indicating a fold-down mechanism. It must feel like one integrated product component, not a bolt-on camera stand. The visible body is elegant and narrow.

On the inner face, embed a very small 3.5-inch portrait touch display with a black narrow bezel. The display must occupy only about one quarter to one third of the visible pillar height and be obviously smaller than a credit card. It should read like a tiny instrument display, not a phone. Show a simple warm-toned Go clock UI and one tiny green status LED below.

At the top, show a clearly separated dual-camera head: a small fisheye proctoring lens on the upper front chamfer facing front/up, and a separate downward-facing recognition lens beneath it. Around the lower downward camera, show a visible restrained terracotta ring light (#C4724A). Add a tiny white recording indicator light. Matte ABS+PC surfaces, precise seam lines, no exposed screws, no giant screen, no pedestal, no accessory-stand appearance.
