Tab 5 — Visualisation (experimental)

Plays back synced trial video with optional overlays: 2D pose keypoints (per-camera detection) and 3D keypoints (triangulated markers reprojected through the camera calibration). Useful for visually checking pose detection and triangulation quality.

🚧 TODO: screenshot with overlays enabled.

Known quirks

• Selecting a different trial sometimes doesn't load the video properly — switch to another camera viewpoint to force a refresh.
• MP4 frame decoding/display via OpenCV is slow — the scrubber and 1 frame back button take time to respond.

🚧 TODO: controls reference (camera selector, overlay toggles, playback/scrubbing) once the tab stabilises. The repo's docs/Visualisation.md has technical details.
