		## 2.1.1 — 2026-08-23

		- Add a dedicated Behavioral suite with composite consumer scenarios and real-Chrome Playground journeys for visible state, editor synchronization, failure, recovery, and user-directed Worker interruption.
		- Prove that easy-stack works with bundlers and without a bundler: bundlers resolve the bare package import normally, while native browser ESM uses an explicit import map with no build or transpilation step.
		- Document the complete normal npm-layout map, HTTP(S) and server-exposure requirements, unsupported <code>file://</code> path, and zero-build/no-transpilation workflow across every browser-facing guide and site area.
		- Add a Given/When/Then native no-bundler acceptance scenario plus static source and deployment assertions that preserve import-map ordering and targets.
		- Keep dependency-conflict and scoped-map testing explicitly not applicable while the published package has zero runtime dependencies; metadata and source guards force reassessment if that changes.
		- Make the release workflow verify and skip an already-published matching immutable version instead of attempting a duplicate publication.

		## Browser package resolution

		easy-stack works with bundlers and without a bundler. Bundlers resolve the bare package import normally. Native browser ESM needs an import map before the module script, but it needs no build or transpilation step:

		```html
		<script type="importmap">
		{
		"imports": {
		"easy-stack": "./node_modules/easy-stack/stack.js"
		}
		}
		</script>
		<script type="module">
		import Stack from 'easy-stack';
		</script>
		```

		These URLs are relative to the HTML document. Serve the application over HTTP(S), expose the mapped files from the server, and do not use `file://`. Version 2.1.1 has zero runtime dependencies, so no dependency entries or scoped nested-dependency map are required.

		7. Use `es5.js` for browser targets that cannot parse private class fields.
		8. For native no-bundler ESM, keep the import map before all module scripts and verify it over HTTP(S).

		easy-stack works with bundlers and without a bundler. Bundlers resolve the bare `easy-stack` import normally. Native browser ESM resolves that same bare import through an import map, with no build or transpilation step:

		```html

		Import-map URLs are relative to the HTML document. Serve the page over HTTP(S), and configure the server to expose the mapped `node_modules` files; `file://` is not a supported path. easy-stack currently has zero runtime dependencies, so the complete normal-layout map needs only the package entry and no scoped nested-dependency map.
