Refactored Studio + impl App into lib.rs (was main.rs). Added a #[wasm_bindgen] start_in_canvas entry plus index.html/Trunk.toml so the same code runs in a browser tab via: rustup target add wasm32-unknown-unknown cargo install trunk cd road_parceling_studio && trunk serve Native still builds with `cargo run -p road_parceling_studio`.
