1//! Shared egui UI components for Eulumdat viewer/editor
2//!
3//! This crate provides reusable egui widgets for visualizing and editing
4//! EULUMDAT (LDT) and IES photometric data. It's designed to be used by:
5//! - Desktop applications (via eframe)
6//! - Web applications (via eframe WASM or embedded in Leptos)
7//!
8//! # Features
9//!
10//! - `3d` - Enable 3D viewer using three-d
11//! - `persistence` - Enable state persistence via serde
12//!
13//! # Example
14//!
15//! ```rust,ignore
16//! use eulumdat::Eulumdat;
17//! use eulumdat_ui::{EulumdatEditor, Theme};
18//!
19//! // In your egui app
20//! fn update(&mut self, ctx: &egui::Context) {
21//!     egui::CentralPanel::default().show(ctx, |ui| {
22//!         self.editor.show(ui, &mut self.ldt);
23//!     });
24//! }
25//! ```
