<model-viewer>

Uses a standard custom HTML element <model-viewer> for declarative, framework-agnostic embedding, making it as simple as adding an image tag, as highlighted in the README's web component focus.

Enables augmented reality experiences directly from the browser on supported devices, allowing users to view models in their real-world environment without native app development, per the key features.

Includes an online editor and fidelity testing tools, such as those in the render-fidelity-tools package, for easier debugging and quality assurance, as noted in the README.

Maintained by Google, ensuring ongoing updates, security patches, and alignment with web standards, which adds credibility and long-term support, as implied in the project description.
