// Minimal web-global shims for Bare (adapted from hyper-proto-peer/lib/bare-globals.js).
// Bare omits TextEncoder/TextDecoder (used at module-load by deps like @noble/curves and by
// atcute's encoding paths). Buffer IS a Bare global, so we back them with it. Import FIRST.
// atcute's P2P handler REPLACES fetch, so we deliberately do NOT shim fetch — only what the
// lexicon/encoding + Response-handling paths need. No-op under Node.
