Lightpanda headless browser written in Zig

I have a research folder of some findings comparing Chrome, headless-shell, lightpanda, jsdom, etc. Lightpanda still did quite well, though with much smaller multiples compared once you've mildly tuned Chrome/headless-shell, but it crashed more often than Chrome and headless-shell.

I haven't yet had time to write it up on The Consensus. So here are some findings you can take or leave.
