Drop a file (or pass ?file=<url>&path=<object>), browse the tree lazily, see a dataset's type, shape, max shape and attributes, and page through its values as 50x12 hyperslab windows (leading dims of 3-D+ data held at chosen indices). build.sh produces pkg/ (not committed) with wasm-bindgen --target web and checks the CLI matches the crate version. test/run.sh builds it and runs test.mjs under Node against the h5py/ netCDF4 fixture (250 checks: every dataset whole and as a strided hyperslab, listings, attributes, error paths, the page's DOM-free helpers), then browser.sh renders the page in headless Chromium for eight objects and checks the DOM. The fixture gains LZ4 (read) and Zstd (refused: links C) datasets and a compound attribute (value null plus its type). ci-test.sh runs it when node and wasm-bindgen exist; the CI container has neither, so CI relies on the native h5py_interop test.
