The entire ai-lab.js file (139KB) was stored as a single Base64-encoded
string instead of actual JavaScript. The browser loaded it as a script
but couldn't parse it — AiLab was never defined, so the batch sim panel
never rendered.
Decoded the file back to its proper 2531-line JavaScript source. The
file already includes auto-initialization at the bottom:
if (document.readyState === 'loading')
document.addEventListener('DOMContentLoaded', AiLab.init);
else AiLab.init();
Also removed the now-redundant DOMContentLoaded listener from
index.html since the JS file handles init itself.
