(sigil browser websocket)

(sigil browser websocket) - Raw browser WebSocket bridge facade

You probably want (sigil websocket) instead: it is the portable, documented WebSocket client (ws-connect, ws-send, ...) and wraps this bridge on WASM builds. This module is the raw platform backend with poll-based event semantics (websocket-receive drains an open/message/ close/error event queue), not the buffered message API.

The JavaScript bridge asset is advertised by package wasm-bridge: metadata. The WASM runtime exposes the %wasm-websocket-* primitives; this module keeps the Sigil-side import path stable.
