Partial A basic HTML parser and CSS selector API is a well-scoped library task. Matching the HTML5 parsing spec and reaching top speed with exact source offsets needs deep parser expertise and extensive testing.
What it would actually take: The stack is probably a systems language such as Rust, Zig, or C, with a tokenizer and tree builder that follow the WHATWG HTML parsing spec. The hard parts are spec conformance on malformed markup and benchmark-driven performance work. Conformance test suites and profiling experience are needed.
