we're using a computer and not allowing it to run code.

...from sources which some people find uncomfortable to be blindly trusting. From a security perspective, it's a huge attack vector - the majority of browser exploits require JS to work.

> seizure-inducing animations

You don't need JavaScript for that.

    div {
      animation: seizure 16.6ms infinite alternate;
    }
    
    @keyframes seizure {
      0%   { background: black; }
      100% { background: white; }
    }
