was made.
Signature technique: Vertical writing + scroll-drawn SVG ensō. The page is one dependency-light HTML document with embedded styles and scripts; this guide is a second self-contained document using the same visual language.
Build sequence
Use one imperfect SVG circle as a structural mark.
Reveal its stroke from scroll progress.
Preserve a complete static ring under reduced motion.
Reproduce it
Copy the parent index.html, preserve the semantic landmarks, then isolate the render loop from the content layer. Keep canvas and 3D surfaces aria-hidden; the story must remain complete without them. Cap device pixel ratio at 2 for expensive scenes, listen to prefers-reduced-motion, and test the final composition at 375px before publishing.
Why this technique
Vertical writing + scroll-drawn SVG ensō is not decoration here: it carries the site's central metaphor. That alignment between subject and mechanism is what keeps a technical showcase from becoming a demo reel.
