vize_musea 0.9.0

//! # vize_musea
//!
//! Musea - Component gallery and documentation for Vize.
//!
//! ## Name Origin
//!
//! **Musea** (plural of museum) represents a gallery space where art is
//! displayed and documented. Similarly, `vize_musea` provides a gallery
//! for Vue components, allowing developers to view and interact with
//! components in isolation - similar to Storybook.
//!
//! ## Concepts
//!
//! - **Art**: A component variation/state (replaces "story")
//! - **Art file** (`*.art.vue`): File defining arts
//! - **Gallery**: Display area for arts
//! - **Palette**: Interactive controls panel
//!
//! ## Performance
//!
//! This crate is optimized for high performance:
//! - **Zero-copy parsing**: All strings are borrowed from source
//! - **Arena allocation**: Uses `vize_carton::Bump` for fast allocation
//! - **Minimal allocations**: Only allocates when absolutely necessary
//! - **Fast byte-level parsing**: Uses `memchr` and `memmem` for O(n) search
//!
//! ## Usage
//!
//! ```rust
//! use vize_carton::Bump;
//! use vize_musea::{parse_art, transform_to_csf};
//! use vize_musea::types::ArtParseOptions;
//!
//! let allocator = Bump::new();
//! let source = r#"
//! <art title="Button" component="./Button.vue">
//!   <variant name="Primary" default>
//!     <Button variant="primary">Click me</Button>
//!   </variant>
//!   <variant name="Secondary">
//!     <Button variant="secondary">Click me</Button>
//!   </variant>
//! </art>
//!
//! <script setup lang="ts">
//! import Button from './Button.vue'
//! </script>
//! "#;
//!
//! // Parse Art file with arena allocator
//! let art = parse_art(&allocator, source, ArtParseOptions::default()).unwrap();
//!
//! // Transform to Storybook CSF
//! let csf = transform_to_csf(&art);
//! println!("Generated: {}", csf.filename);
//! ```
//!
//! ## Features
//!
//! - Zero-copy parsing of `*.art.vue` files
//! - Type-safe variant definitions
//! - Storybook CSF 3.0 export
//! - Visual Regression Testing (VRT) support
//! - Interactive props palette
