devinilabs/sylva-hero ? reverse-engineered prompt

Build me a standalone landing page that runs as a plain HTML file with no build step and no framework.

It should show a lush mossy branch scene in Three.js with drifting pollen, a butterfly, floating content cards, and a subtle parallax camera effect as you scroll or move around. Keep everything local so it works offline once served over HTTP, including the font and image assets. I want it to feel like a polished hero section from a premium site, with smooth animation, good typography, and no console errors.

Please make it easy to run with a simple local server, and don’t turn it into a React app or anything that needs compilation. If you need to check anything, look up the current Three.js docs online. Also keep the attribution and license notes in place since this is an extracted component from another project.
