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.

+### Better `os.arch()` for node and the browser -- detect OS architecture
+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/arch2.svg)](https://saucelabs.com/u/arch2)
+
+This module is used by [WebTorrent Desktop](http://webtorrent.io/desktop) to
+determine if the user is on a 32-bit vs. 64-bit operating system to offer the
+right app installer.
+
+In Node.js, the `os.arch()` method (and `process.arch` property) returns a string
+identifying the operating system CPU architecture **for which the Node.js binary
+was compiled**.
+
+This is not the same as the **operating system CPU architecture**. For example,
+you can run Node.js 32-bit on a 64-bit OS. In that situation, `os.arch()` will
+return a misleading 'x86' (32-bit) value, instead of 'x64' (64-bit).
+
+Use this package to get the actual operating system CPU architecture.
+
+**BONUS: This package works in the browser too.**
+
+## install
+
+```
+npm install arch
+```
+
+## usage
+
+```js
+var arch = require('arch')
+console.log(arch()) // always returns 'x64' or 'x86'
+```
+
+In the browser, there is no spec that defines where this information lives, so we
+check all known locations including `navigator.userAgent`, `navigator.platform`,
+and `navigator.cpuClass` to make a best guess.
+
+If there is no *affirmative indication* that the architecture is 64-bit, then
+32-bit will be assumed. This makes this package perfect for determining what
+installer executable to offer to desktop app users. If there is ambiguity, then
+the user will get the 32-bit installer, which will work fine even for a user with
+a 64-bit OS.
+
+For reference, `x64` means 64-bit and `x86` means 32-bit.
+
+Here is some history behind these naming conventions:

+## Node.js proposal - `os.sysarch()`
+
+Note: There is
+[a proposal](https://github.com/nodejs/node-v0.x-archive/issues/2862#issuecomment-103942051)
+to add this functionality to Node.js as `os.sysarch()`.
