Subject: [PATCH 1/2] chore: vendor prebuilt multiplayer bundles for CDN
 pinning

The @jspsych-multiplayer packages cannot currently be loaded from npm:
plugin-multiplayer-reference-game is unpublished (404), and the published
0.1.0 builds of the local adapter, sync and role plugins predate the
jsPsych.multiplayer namespace migration, so they are incompatible with the
#3694 preview core these experiments pin.

Vendor all four browser bundles (built from jspsych-multiplayer@69c0d7b) so
both experiment files load from a plain URL with no build step. See
vendor/README.md for provenance and removal steps once PR #35 publishes.

+# vendor/ — temporary pinned builds
+
+These are **prebuilt browser bundles** of the `@jspsych-multiplayer/*` packages,
+committed here so the experiment files in this repo are runnable from a plain URL
+(via jsDelivr) without a local build step.
+
+## Why these exist
+
+At the time of writing, these packages cannot be loaded from npm:
+
+| package | npm status |
+| --- | --- |
+| `plugin-multiplayer-reference-game` | **not published** (404) |
+| `adapter-multiplayer-local` | published `0.1.0`, but **pre-namespace-migration** |
+| `plugin-multiplayer-sync` | published `0.1.0`, but **pre-namespace-migration** |
+| `plugin-multiplayer-role` | published `0.1.0`, but **pre-namespace-migration** |
+
+The experiment files pin jsPsych core to a preview build of
+[jspsych/jsPsych#3694](https://github.com/jspsych/jsPsych/pull/3694), which moved
+the multiplayer API to the `jsPsych.multiplayer` namespace. The published `0.1.0`
+bundles predate that migration and still call the old core API, so mixing them
+with the pinned core does not work.
+
+Vendoring all four keeps the plugin bundles and the pinned core consistent.
+
+## Provenance
+
+Built with `npm run build` from `jspsych/jspsych-multiplayer` at commit
+[`69c0d7b`](https://github.com/jspsych/jspsych-multiplayer/commit/69c0d7b).
+Each file is that package's `dist/index.browser.min.js`, renamed.
+
+## Removing this directory
+
+Once [PR #35 ("Version Packages")](https://github.com/jspsych/jspsych-multiplayer/pull/35)
+merges and republishes the packages, this directory should go away:
+
+1. Repoint the four `<script>` tags in `reference-game-hawkins.html` and
+   `reference-game-cwg.html` back to
+   `https://cdn.jsdelivr.net/npm/@jspsych-multiplayer/<pkg>@<version>/dist/index.browser.min.js`.
+2. Delete `vendor/`.
+
+Do not edit these files by hand — rebuild from source instead.

Subject: [PATCH 2/2] chore: load multiplayer plugins from vendor/ via jsDelivr

Repin the four @jspsych-multiplayer script tags in both experiment files from
npm (unpublished / pre-migration) to the SHA-pinned vendor/ bundles added in
the previous commit, and replace the stale "pin to a real published version"
TODO with the actual situation.

Both files now load with no build step and no 404s.
