Doesn’t it just call `less`?

bat does not look like a pager: https://github.com/sharkdp/bat?tab=readme-ov-file#automatic-...

I like it a lot more than `less`, but unfortunately it's always a lot slower when first opening really large files. I'm not sure if it's eagerly loading the whole thing (maybe because that's needed for AST parsing in the case of syntax highlighting, although it happens even on files without highlighting), but there are times I have to swap to `less` still.
