Every sign, rendered clean and clear.
A precise avatar that reproduces handshapes, finger positions, and movement for each sign — driven by a MediaPipe-style landmark stream and drawn as crisp vectors that stay sharp at any size.
- Accurate handshapes and finger articulation for every sign
- Crisp vector rendering that stays sharp at any size
- Driven by a MediaPipe-style landmark stream
- Same renderer for embedded and standalone use
