Render HTML/CSS/Canvas Animations directly to Timeline Media (ProRes 4444)

Context: Building dynamic, web-based motion graphics (HTML5/React) inside Premiere Pro using CEP is incredibly powerful for live-sports and broadcast editors. However, there is a massive missing link when it comes to motion.

The Feature Request: A native wrapper function inside the CEP Extension that allows us to command Premiere to "record" or "bake" our panel's DOM (or a hidden webview) into a video file with an alpha channel.

The Problem: Currently, if I have a 3-second CSS animation (like a team logo bouncing with a glow), there is no native way to bake this HTML animation into a transparent video clip on the Premiere timeline.

The Solution: We need an API method to capture a web animation at 60 FPS for X seconds, and losslessly import that result directly onto the active sequence as a transparent video clip (e.g., ProRes 4444). This addition alone would make Premiere Pro the single most powerful NLE in the world for web-to-video workflow integration.
