Explore web rendering surface via Servo (e.g. web page PiP)

[staging-devin-ai-integration]

Summary

Investigate integrating a web rendering surface into StreamKit's compositor, enabling use cases like rendering web pages as picture-in-picture overlays or interactive web content within media pipelines.

Motivation

A web rendering surface would allow embedding arbitrary web content — dashboards, chat overlays, browser-based widgets — directly into composited output. This opens up a huge design space for dynamic, web-driven overlays without needing custom node development for each use case.

Direction to Explore

• Servo as the candidate web engine — it's written in Rust, embeddable, and designed for integration into other applications.
• How Servo's rendering output could be captured and fed into StreamKit's compositor as a layer.
• Feasibility of interactive (input-forwarding) vs. passive (render-only) modes.
• Resource/performance implications of running a web engine within the media pipeline.
• Web page PiP as a concrete first use case.

Scope

This is a high-level roadmap item for investigation and design. No implementation is expected initially — the goal is to evaluate feasibility and define an integration architecture.
