windjammer-ui 0.3.6

//! Minimal Working Counter - Pure Rust, no Windjammer transpilation needed
//! This demonstrates that the UI framework actually works
//!
//! To build and run:
//! ```bash
//! cd crates/windjammer-ui
//! wasm-pack build --target web --dev
//! python3 -m http.server 8000
//! # Open http://localhost:8000/examples/minimal_working.html
//! ```
