 ## What’s inside
 - **Main app (`app.py`)** — runs full inference with adjustable thresholds, overlays, and camera assumptions; requires >8GB VRAM (assuming default 1024 px processing resolution); runtime is ~2000 ms per image.
-- **Sample data (`examples/visloc/`)** — 5 VISLOC frames bundled for quick testing in the Space.
