ftxui

FTXUI is organized into three modules, each building upon the previous:

1. ftxui/screen - Low-level rendering
2. ftxui/dom - Layout and composition
3. ftxui/component - User interaction

# ftxui/screen

Defines:

- `ftxui::Screen`: a 2D grid of styled characters.
- `ftxui::Pixel`: the unit of rendering.
- Helpers like `ftxui::Color` and `Dimension`.

Use for direct terminal drawing and styling.

# ftxui/dom

Provides:

- `ftxui::Element`: a tree structure for layout and UI.
- Composable and responsive elements.
- `Render()` to draw onto a `Screen`.

Ideal for structured, styled UIs.

Modules can be used independently, or together: `screen → dom → component`.
