Observation: Teal would make a great scripting language for a simpler web browser, one not based on JavaScript... maybe something like the 'Surf' web browser: (https://surf.suckless.org/).

Also, there should exist the capability to compile Teal to Wasm... or at least Teal to Lua to Wasm(!)... to that end, there exists the following GitHub repo (but I'm not sure if it's 100% operational yet):
