A glass tube laid across the page that fills with liquid as you scroll through the story: the liquid's front edge wobbles and leans with how fast you scroll, bubbles rise inside it, and each milestone below lights up the moment the liquid reaches its mark.
Velocity-driven slosh: `tilt += (v × 900 − tilt) × 0.08; tilt *= 0.94` where v is scroll progress per frame, so a fast flick leans the meniscus forward and it rocks back when you stop, while the fill itself is a separate spring on X.
From prompt to a block in your page.
The preview is the shipped block inside a neutral demo page. Scroll, hover, drag: everything is live.
Token sets re-tint the block live. The prompt carries the one you chose.
A paste-in snippet, or a component for Next.js, React, Vue, Astro, WordPress, Shopify or Webflow.
It quotes the block's markup, styles and script verbatim with the tokens and the rules that keep it self-contained.
Add the head lines it names, paste the block, replace the placeholder copy. Tokens live on :root.
