This table is informative as to exactly what lightpanda is: https://lightpanda.io/blog/posts/what-is-a-true-headless-bro...

TL;DR: It does the following:

- Fetch HTML over the network

- Parse HTML into a DOM tree

- Fetch and execute JavaScript that manipulates the DOM

But not the following:

- Fetch and parse CSS to apply styling rules

- Calculate layout

- Fetch images and fonts for display

- Paint pixels to render the visual result

- Composite layers for smooth scrolling and animations

So it's effectively a net+DOM+script-only browser with no style/layout/paint.

Definitely fun for me to watch as someone who is making a lightweight browser engine with a different set of trade-offs (net+DOM+style/layout/paint-only with no script)
