The web part is the security model and the tradeoffs between security and performance. PNaCL was in browsers but not "web" for this reason.
Like the assembly part means low-level and meant as a compilation target, not CPU instructions.
So websssembly is an assembly language for the web, like webgl is opengl for the web and webgpu are gpu APIs for the web. And behold none of those can access DOM APIs
