A minimal Flexbox-inspired layout engine for Rust GUI development.

This crate provides a small, predictable layout system designed for
custom GUI frameworks, editors, and experimental UI engines.

> [!NOTE]
> This crate is under active development; patch releases may be frequent.

## Features


- Flex layout (Row / Column)
- `flex_grow` and `flex_basis`
- Fixed size and flexible size mixing
- Min / max size constraints
- Margin and padding (CSS-like spacing)
- Block layout
- Recursive tree-based layout
- Parent-relative positioning
- Row and column gaps (`row_gap` / `column_gap`)
- Justify content (`justify_content`) and align items (`align_items`)

## Non-goals


- Full CSS compatibility
- Inline or text layout
- Absolute / fixed positioning
- Web rendering or HTML/CSS parsing

## Design goals


- Simple and explicit layout rules
- Easy to reason about and debug
- Suitable for custom renderers (wgpu, skia, etc.)
- No dependency on web standards or DOM

## Example


```rust
use layout::*;

LayoutEngine::layout(&mut root, 800.0, 600.0);
```

For more examples and to understand the behavior of gaps, alignment, and sizing,
see the unit tests in the [`tests/`](tests/) directory. They provide practical usage patterns and expected layouts.
