Camera on Screen 0.2.1

AI effects require an NVIDIA RTX GPU; non-RTX installs run as a plain webcam overlay. Multi-GPU build (Turing/Ampere/Ada/Blackwell engines bundled) — verified on Ampere (sm86); other RTX arches are best-effort and grey out gracefully if an engine fails to load.

Bundled NVIDIA Maxine runtime (VFX 1.2.0.0 + AR 1.1.1.0) is governed by the 2025 NVIDIA Software License Agreement + Open/Community Model Licenses — see THIRD-PARTY-NOTICES.md.
