Make the lower rows answer the top row, each one a beat later, like a canon.

Figuring out delay semantics
**Figuring out delay semantics**

I need to determine if delay semantics likely track the delays when I modify the wrapper. Maybe I can implement a loop and then verify if the delay works properly by checking the preview. It seems like a bit of a puzzle, but I think by iterating through this process, I could get a clearer understanding of how these components interact. I'm curious to see if everything aligns correctly in the end!

Next tool: `CaptureRenderWindowRequest`

Done—the accent now travels down the rows like a canon:

- **Top:** leads.
- **Middle:** follows one beat later, **0.5 s**.
- **Bottom:** follows another beat later, **1 s** behind the top.

The live view retains the cream/vermilion bars on black, with the bottom row visibly extended in its answering accent. Timed previews confirm the top → middle → bottom sequence. Compilation and visual checks passed.
