## What it is
Oat is an ultra-lightweight (~10KB min+gz), zero-dependency UI component library built on semantic HTML, CSS, and vanilla JS WebComponents. It styles native elements contextually without classes, requiring no framework or build step.

## Use cases
- build a decent-looking web app without a JS framework
- style semantic HTML with no CSS classes
- add a lightweight UI kit to a server-rendered site
- avoid npm dependency bloat in frontend projects
- get accessible components with keyboard navigation out of the box
- quickly theme a dashboard with CSS variables and dark mode

## When to choose
- you want zero dependencies and no build tooling
- you prefer semantic HTML over class-heavy markup
- you need a tiny footprint for dashboards or internal tools
- you value accessibility and standards-based vanilla CSS/JS

## When to avoid
- you need a rich component ecosystem or complex state management
- you're building a highly interactive SPA with React/Vue
- you require a stable v1 API (project is pre-v1 with breaking changes)
- you need extensive custom design beyond CSS variable theming
