1//! # dotloom-engine
2//!
3//! The headless Dotloom engine. It owns the only editable copy of a document and
4//! runs every change through one pipeline:
5//!
6//! ```text
7//! commands → working overlay → structural validation → solve (affected component)
8//!          → independent hard-rule check → atomic commit → revision + events
9//! ```
10//!
11//! A failed transaction leaves the document untouched. Undo/redo apply stored
12//! before/after states without re-solving. Drags produce transient previews and a
13//! single history entry. Plugin entity types are data ([`EntityTypeDef`]) compiled
14//! from a typed expression language; no host code runs inside the solver.
15//!
16//! The engine has no DOM, window or GPU dependency.
