1//! Layout engine — computes size and position for every element.
2//!
3//! Chrome equivalent: `blink/renderer/core/layout/` + `ng/` (`LayoutNG`).
4//!
5//! # Architecture (DOM IS the layout tree)
6//!
7//! ```text
8//! DOM Tree (Document)              Fragment Tree
9//! ───────────────────              ──────────────
10//! Storage<LayoutNodeData>          (final positions)
11//!   .style (taffy::Style)
12//!   .cache (taffy::Cache)     ──layout()──►  Fragment (Arc, immutable)
13//!   .layout_children               TextFragment
14//!   .unrounded_layout              Fragment
15//!
16//!   Taffy reads/writes LayoutNodeData
17//!   directly via DocumentLayoutView
18//! ```
19//!
20//! No separate `LayoutTree`. Taffy's trait implementations
21//! (`LayoutPartialTree`, `CacheTree`, etc.) are on `DocumentLayoutView`
22//! which wraps `&mut Document` + `&LayoutContext`.
23//!
24//! # Module structure
25//!
26//! | Module | Purpose |
27//! |--------|---------|
28//! | [`node_data`] | Per-node layout data (style, cache, layout results) |
29//! | [`document_layout`] | Taffy trait impls on Document, resolve pipeline |
30//! | [`fragment`] | Immutable output flowing up |
31//! | [`result`] | Algorithm output wrapper |
32//! | `algo::shared` | ComputedValues → taffy::Style conversion |
33//! | [`inline`] | Text measurement, font system |
34//! | [`hit_test`](mod@hit_test) | Fragment tree hit testing |
