HTTP and IPFS browser readers

Use RemoteIndex for HTTP-hosted index files or IpfsIndex with application fetch and size callbacks. Both readers are read-only. Create compatible index files with Summa 2, then publish a complete, immutable snapshot.

The browser WASM guide includes current imports, method names, callback types and caching methods. HTTP hosting must support range requests and CORS when origins differ. The reader’s optional IndexedDB cache does not make all network traffic private.

IPFS transport is supplied by your application. Summa 2 does not bundle an IPFS node or an HTTP gateway. The original guide’s aiosumma, YAML configuration and old web bundle commands have been replaced by the current WASM API.
