-- `engine`: the GPX engine, plain Rust. Tested natively: `cargo test`.
-- `wasm`: the interface to the web page, compiled to WebAssembly.
+The GPX engine: plain Rust, no knowledge of who uses it. Tested natively with `cargo test` (from
+here or from the root).
 
-```
-wasm-pack build wasm --target bundler --out-dir ../pkg

-The interface is tested in Node (it needs `wasm-pack`, which fetches the test runner the first time):

-```
-wasm-pack test --node wasm

+- `src/core`, `src/engine`, `src/storage`: the engine itself.
+- `src/api`: the interface to the engine that the frontends (`../wasm`, `../tauri`) share. Each
+  function takes the engine and typed arguments, and gives plain data (`api::dto`, serde types, or
+  slices for the numeric buffers). A frontend only converts what crosses: ids from strings or
+  bytes, results to JS objects or JSON, slices to typed arrays or raw bytes.
