## What it is
LuLu UI is a cross-browser, cross-framework native JavaScript and CSS UI component library from China Literature (Yuewen), offering themes (Edge, Pure, Peak, Hope) built on Web Components and vanilla HTML. It is plug-and-play via CDN script/CSS tags, npm, or ES module imports, with minimal APIs and no framework dependency.

## Use cases
- add UI components to a plain HTML site without a build step
- use dialog, date picker, select, validation components in React or Vue projects
- build a PC website for external users with lightweight vanilla JS components
- need IE8/IE9 compatible UI components
- learn how UI components are built with native JavaScript and CSS
- drop-in form validation and date picker without npm install

## When to choose
- you want plug-and-play components with plain HTML/CSS and minimal API
- your project uses React/Vue but you prefer framework-agnostic native components
- you need legacy IE browser support (Peak/Pure themes)
- you prefer copy-paste, low-learning-curve UI code you can freely modify

## When to avoid
- you need a full-featured component ecosystem with state management like Ant Design or Element UI
- your project is mobile-first SPA requiring complex theming and TypeScript types
- you rely on semantic versioning and strict upgrade paths (LuLu has no version concept)
