+/**
+ * Browser-bundle gate. Confirms that the `./wasm` subpath entry point
+ * compiles cleanly under `Bun.build({ target: "browser", format: "esm" })`
+ * AND that the produced bundle does not pull in any `node:*` specifier,
+ * Hono, or OTel-SDK dependency.
+ *
+ * The lint script `scripts/lint/check-wasm-subpath-deps.ts` is the
+ * static-analysis counterpart; this test is the runtime confirmation
+ * via the actual Bun bundler.
