Working with this library

Checked 2026-10-28 against official sources. Official lucidui-dev/lucidui README verifies @lucidui-dev/core, signal-based DOM rendering, ES-module or bundled JavaScript/CSS integration, UI and chart subpaths, and an optional @lucidui-dev/core/react boundary for embedding in React/Next.js. This is its own runtime, not a drop-in React component collection, and is unrelated to AppNexus/Xandr lucid-ui. MIT source is free with retained notices. Status is explicitly early/experimental; APIs may change before 1.0. The bridge/Builder integration is optional and was not installed or executed. Editorial: distinctive for small, agent-readable interfaces and predictable diagnostic feedback; evaluate ecosystem maturity, migration cost, focus behavior and performance yourself. Website bundle-size, token-count, agent-compatibility and comparison figures are upstream claims, not independently reproduced benchmarks or endorsements.
