✅ 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

+
+Supports Prism highlighting in Astro projects
+
+## Component
+
+This package exports a component to support highlighting inside an Astro file. Example:
+
+```astro
+---
+import { Prism } from '@astrojs/prism';
+---
+
+<Prism lang="js" code={`const foo = 'bar';`} />
+```
+
+## Internal
+
+This package exports a `runHighlighterWithAstro` function to highlight while making sure the Astro language is loaded beforehand
+
+```typescript
+import { runHighlighterWithAstro } from '@astrojs/prism';
+
+runHighlighterWithAstro(
+  `
+  ---
+    const helloAstro = 'Hello, Astro!';
+  ---
+
+  <div>{helloAstro}</div>
+`,
+  'astro',
+);
+```
