// The Cloudflare Workers free plan has a 3 MiB size limit — without
// these externals, the Worker bundle is ~19 MiB (mostly @stellar/stellar-sdk
// and wallet SDKs). These packages are lazy-imported at runtime via
// dynamic import(), so they don't need to be in the initial bundle.
//
// Note: defineCloudflareConfig() already sets edgeExternals: ["node:crypto"].
// We merge our extras in rather than replacing the array — otherwise
// ensureCloudflareConfig() fails validation because node:crypto is missing.
