Automating space layouts

I have a preferred space layout in mind: 3 vertical columns, where column A takes up 50% of the space, then B and C each take up 25%. Clearly this is just a node and two leaves, but how do I force a specific window or application to always be in column A? I tried something like this:

`yabai -m signal --add event=window_created app='Google Chrome' action='yabai -m window $YABAI_WINDOW_ID --warp west'`

but it's either not triggering or I'm misunderstanding how I'm supposed to handle this.

Start by checking how the `window_created` signal and `yabai -m window $YABAI_WINDOW_ID --warp west` command are expected to interact. Verify the signal with a Google Chrome window and confirm whether the created window reaches the intended column; done means the requested application is reliably placed in column A.
