## What is Melker?
A TUI framework where you write terminal apps the way you'd write a web page. One .melker file — markup, stylesheets, scripts. No compile step, no build system.
- **HTML-like** markup with 20+ components, **CSS stylesheets** with @media queries, **Flexbox layout** engine
- **Permission** sandbox per app
- F12 **Dev Tools** (inspect, logs, policy), **LSP** for editor support
- **Piping** and stdout mode
- **Graphics** with Sextant, Sixel, Kitty and iTerm2 support
- Canvas **shaders** and **image** rendering
- **Markdown** and **Mermaid** diagrams
- Optional **AI assisted** screen reader
