LEMA-DS blocksfor shadcn/ui.

LEMA-DS is the official design system of LEMA, the Laboratório de Economia e Modelagem Aplicada at the Universidade Federal da Paraíba in Brazil. It's a React component library built on shadcn/ui and Radix UI, documented in a Storybook with Portuguese descriptions, and its registry holds hundreds of ds-prefixed components alongside the standard shadcn primitives. The range goes well past marketing sections, with stat cards and charts (including box plot, bullet and candlestick charts), billing and dashboard views, blog layouts, a checkout, an audio player and browser mockups.

The blocks listed here are page sections: headers including a command-bar variant, a floating navbar, glowing and layered heroes, a sticky feature list, a bento contact section, registration and auth cards, an AI chat, cookie and top banners, and several footers. Items install with the shadcn CLI or the lab's own ds-sync tool.
