+### Features
+
+- **Two install paths.** Existing ESM via npm, plus a new IIFE bundle (`dist/wproofreader-learnosity.min.js`) served from jsDelivr, exposing `window.LearnosityWProofreader.init` for host apps that load the connector via a `<script>` tag (PHP, Python, Java, ASP.NET, Ruby, classic HTML). About 5 KB minified, no runtime dependencies. Built with esbuild via `npm run build`; produced automatically at `npm publish` time via the `prepack` hook.

+### Via `<script>` tag (non-Node host apps)
+
+For host apps where adding a bundler is overkill (classic HTML, PHP, Python, Java, ASP.NET, Ruby), load the connector from jsDelivr:
+
+```html
+<script src="https://cdn.jsdelivr.net/npm/@webspellchecker/wproofreader-learnosity@1.2.0/dist/wproofreader-learnosity.min.js"></script>
+<script>

+  });
+</script>
+```
+
+The bundle exposes a single global, `window.LearnosityWProofreader`, with the same `init` method. About 5 KB minified, no runtime dependencies. jsDelivr serves from npm, so the pinned URL above resolves once the package is published.
