Follow-up: my three.js product page was too heavy for phones. Reworked it, now it runs smoothly on mobile.

Few days ago, I shared a 3D product page I built in vanilla three.js with Claude Code. A few of you pointed out it struggled on phones, and you were right: frame rate dropped badly on mobile. That's what I like about this workflow. I can build from what I see, without having to think of everything ahead, which was paralyzing me, over thinking and planning all future blocks. Now I can just take it step by step, and fix it as I'm going. Again, I want a working prototype, not a clean shippable app. Do you not agree ?
