- Rename `esm` to `esm-browser`
- Add runtime-only build for `esm-browser`
- Add default CDN alias for jsdelivr

 - **`vue(.runtime).global(.prod).js`**:
   - For direct use via `<script src="...">` in the browser. Exposes the `Vue` global.
-  - Note: global builds are not [UMD](https://github.com/umdjs/umd) builds.  They are built as [IIFEs](https://developer.mozilla.org/en-US/docs/Glossary/IIFE) and is only meant for direct use via `<script src>`.
-  - **`vue.global.js`**: the "full" build that supports compiling templates on the fly.
-  - **`vue.runtime.global.js`**: runtime only, does not include runtime template compilation support. Use this if you are not using a bundler, but somehow pre-compiling your template.
+  - Note that global builds are not [UMD](https://github.com/umdjs/umd) builds.  They are built as [IIFEs](https://developer.mozilla.org/en-US/docs/Glossary/IIFE) and is only meant for direct use via `<script src="...">`.
+  - In-browser template compilation:
+    - **`vue.global.js`** is the "full" build that includes both the compiler and the runtime so it supports compiling templates on the fly.
+    - **`vue.runtime.global.js`** contains only the runtime and requires templates to be pre-compiled during a build step.
+  - Inlines all Vue core internal packages - i.e. it's a single file with no dependencies on other files. This means you **must** import everything from this file and this file only to ensure you are getting the same instance of code.
+  - Contains hard-coded prod/dev branches, and the prod build is pre-minified. Use the `*.prod.js` files for production.
 
-- **`vue.esm(.prod).js`**:
-  - For usage via native ES modules imports (in browser via `<script type="module">`, or via Node.js native ES modules support in the future)
-  - Inlines all dependencies - i.e. it's a single ES module with no imports from other files
-    - this means you **must** import everything from this file and this file only to ensure you are getting the same instance of code.
-  - Hard-coded prod/dev branches, and the prod build is pre-minified (you will need to use different files for dev/prod)
+- **`vue(.runtime).esm-browser(.prod).js`**:
+  - For usage via native ES modules imports (in browser via `<script type="module">`.
+  - Shares the same runtime compilation, dependency inlining and hard-coded prod/dev behavior with the global build.
 
 ### With a Bundler
 
 - **`vue(.runtime).esm-bundler.js`**:
+
   - For use with bundlers like `webpack`, `rollup` and `parcel`.
   - Leaves prod/dev branches with `process.env.NODE_ENV` guards (must be replaced by bundler)
   - Does not ship minified builds (to be done together with the rest of the code after bundling)
-  - imports dependencies (e.g. `@vue/runtime-core`, `@vue/runtime-compiler`)
-    - imported dependencies are also `esm-bundler` builds and will in turn import their dependencies (e.g. `@vue/runtime-core` imports `@vue/reactivity`)
-    - this means you **can** install/import these deps individually without ending up with different instances of these dependencies.
-  - **`vue.runtime.esm-bundler.js`**: runtime only, does not include runtime template compilation support. **This is the default entry for bundlers (via `module` field in `package.json`)** because when using a bundler templates are typically pre-compiled (e.g. in `*.vue` files).
-  - **`vue.esm-bundler.js`**: includes the runtime compiler. Use this if you are using a bundler but still want runtime template compilation (e.g. in-DOM templates or templates via inline JavaScript strings).
+  - Imports dependencies (e.g. `@vue/runtime-core`, `@vue/runtime-compiler`)
+    - Imported dependencies are also `esm-bundler` builds and will in turn import their dependencies (e.g. `@vue/runtime-core` imports `@vue/reactivity`)
+    - This means you **can** install/import these deps individually without ending up with different instances of these dependencies, but you must make sure they all resolve to the same version.
+  - In-browser template compilation:
+    - **`vue.runtime.esm-bundler.js` (default)** is runtime only, and requires all templates to be pre-compiled. This is the default entry for bundlers (via `module` field in `package.json`) because when using a bundler templates are typically pre-compiled (e.g. in `*.vue` files).
+    - **`vue.esm-bundler.js`**: includes the runtime compiler. Use this if you are using a bundler but still want runtime template compilation (e.g. in-DOM templates or templates via inline JavaScript strings). You will need to configure your bundler to alias `vue` to this file.
