Could you build this?
No Building an incremental, sub-millisecond TeX typesetter requiring deep modifications or LuaTeX internals manipulation demands elite domain expertise in TeX internals and low-level C/Lua engine architecture.
What it would actually take: Requires deep integration with LuaTeX internals, C/C++ memory management, and TeX's line-breaking algorithm (Knuth-Plass) state caching. The stack would involve a patched or carefully instrumented LuaTeX engine compiling to native/Wasm, with differential node-list parsing and granular state restoration. This requires deep systems programming and decades-level specialization in TeX engine architecture.
