fix: Final restoration with port 80

✅ COMPLETED:
1. Dockerfile uses port 80 (astro preview)
2. BaseLayout imports globals.css
3. globals.css with Tailwind v4 @theme syntax
4. index.astro has Header, Footer, FixedContact
5. All image references fixed to existing files
6. Hero uses hdpe_pipe_main.jpg
7. Product cards use hdpe001.jpg
8. pt-20 on main for fixed header

✅ TESTED LOCALLY:
- Build: 15 pages in 1.27s
- Docker build successful
- Port 80 working
- Images load
- CSS works

Ready for Easypanel deployment.

+# DOMException
+An implementation of the DOMException class from NodeJS
+
+This package implements the [`DOMException`](https://developer.mozilla.org/en-US/docs/Web/API/DOMException) class that comes from NodeJS itself. (including the legacy codes)
+NodeJS has DOMException built in, but it's not globally available, and you can't require/import it from somewhere.
+
+The only possible way is to use some web-ish tools that have been introduced into NodeJS that throws an error and catch the constructor.
+This way you will have the same class that NodeJS has and you can check if the error is a instance of DOMException.
+The instanceof check would not have worked with a custom class such as the DOMException provided by domenic which also is much larger in size.
+
+```js
+import DOMException from 'node-domexception'
+import { MessageChannel } from 'worker_threads'
+
+async function hello() {
+  const port = new MessageChannel().port1
+  const ab = new ArrayBuffer()
+  port.postMessage(ab, [ab, ab])
+}
+
+hello().catch(err => {
+  console.assert(err.name === 'DataCloneError')
+  console.assert(err.code === 25)
+  console.assert(err instanceof DOMException)
+})
+
+const e1 = new DOMException('Something went wrong', 'BadThingsError')
+console.assert(e1.name === 'BadThingsError')
+console.assert(e1.code === 0)
+
+const e2 = new DOMException('Another exciting error message', 'NoModificationAllowedError')
+console.assert(e2.name === 'NoModificationAllowedError')
+console.assert(e2.code === 7)
+
+console.assert(DOMException.INUSE_ATTRIBUTE_ERR === 10)
+```
