Clean Up Two white bars flashing on page load
Cause:
bundle.js creates 2 input elements as part of the WebKit exploit (CVE-2022-22620).
The PS4 browser briefly renders them as visible white bars before they are removed.
Fix:
Added this CSS to index.html inside the <style> block before </style>:
input { position: fixed; left: -9999px; opacity: 0; }
This hides them off-screen. Exploit still works normally.
