WebGPU canvas renders 7,000 live DOM frames with 2M+ elements at 120fps

eminimnim's team demoed a WebGPU canvas rendering 7,000 real HTML/CSS frames with over 2 million elements at 120 fps, with every frame running the full interactive app.
Key points:
- A custom HTML renderer supports every CSS property (blurs, shadows, gradients, 3D transforms), claiming full parity with Chrome's renderer
- A custom bundler extracts HTML/CSS/JS from almost any codebase and optimizes it for canvas
- Essentially a mini browser written in Rust running inside the browser, with the entire pipeline owned in-house
- The author calls it two years of compounding infrastructure work
