// The browser's copy of the ESM-only p2p stack, as one chunk.
//
// ird.p2p.db imports helia, @orbitdb/core and the libp2p packages at runtime
// through the global `ird_dyn_import` helper (Node resolves the bare
// specifiers from node_modules). A browser cannot resolve bare specifiers, so
// a page bundles this entry with esbuild into one classic script exposing
// `irdVendor`, loads it BEFORE the compiled ClojureScript, and points the
// helper at it (README, "Browser peers"):
//
//   esbuild browser/vendor-entry.mjs --bundle --format=iife --global-name=irdVendor \
//           --platform=browser --outfile=vendor.js
//   <script src="vendor.js"></script>
//   <script>globalThis.ird_dyn_import = n => Promise.resolve(irdVendor.load(n))</script>
//   <script src="app.js"></script>
//
// Loading it first matters: evaluating the chunk installs Node's Buffer (the
// `buffer` package) as a global, and the byte helpers of ird-p2p-cljs use
// Buffer as soon as their namespaces load. (An ESM build — --format=esm, then
// `import './vendor.mjs'` statically before the app — works the same way.)
//
// What is NOT here, on purpose: @libp2p/tcp and @libp2p/mdns (no such thing
// in a browser), bootstrap, kad-dht, any public gateway or delegated router.
