# Depth Stack Hero

> Split product hero with a 3D stack of live UI cards (revenue chart, deploy progress, payment toast) in real perspective. The stack tilts toward the cursor on springs and its layers separate in Z when hovered; bars grow and the deploy bar loops.

2. Put an API key from https://www.assembli.design/account in `.env.local` as `ASSEMBLI_API_KEY=asm_…`.

Then install with the shadcn CLI (writes `components/depth-stack-hero/depth-stack-hero.tsx` and installs dependencies):
