+// Voxer changes from upstream:
+//   1. `process.binding('http_parser')` was removed in Node 16+
+//      ("No such module: http_parser"). When that fails we now load
+//      `HTTPParser` from `node:_http_common` (Node 16+) and the
+//      methods list from `require('http').METHODS`, keeping the
+//      `mode === 'modern'` numeric kOn* path. The previous fallback
+//      to `mode = 'unsupported'` used string event names that the
+//      modern parser does not expose, so `parser[kOnHeadersComplete]`
+//      was undefined and any request crashed the process with
+//      `TypeError: this[kOnHeadersComplete] is not a function`.
+//   2. `new Buffer(0)` -> `Buffer.alloc(0)` (the legacy form is removed in
+//      modern Node).
