Casca

Casca is a CSS-first, zero-JavaScript library of data components — charts, tables, dashboards, KPIs, and controls — for server-rendered pages.

• Zero JavaScript. All interactive behavior uses native HTML controls, :checked, :has(), and server round-trips.
• Zero dependencies. One CSS bundle. No npm tree, no framework.
• Zero global side effects. Every selector is scoped to .casca.
