KiThePlot 0.5.0

//! Tiny, embeddable plot redactor crate.
//!
//! Architecture summary:
//! - `model`: domain data structures (`DataTable`, plot configuration, styles).
//! - `controller`: action handling, validation, undo/redo, import/export orchestration.
//! - `view`: egui UI composition and action emission.
//!
//! Dataflow:
//! `View -> Action -> Controller -> Model`, then View re-renders from model snapshot.
