✅ 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

+/**
+ * Astro Telemetry -- System Info
+ *
+ * To better understand our telemetry insights, Astro collects the following anonymous information
+ * about the system that it runs on. This helps us prioritize fixes and new features based on a
+ * better understanding of our real-world system requirements.
+ *
+ * ~~~
+ *
+ * Q: Can this system info be traced back to me?
+ *
+ * A: No personally identifiable information is contained in the system info that we collect. It could
+ * be possible for someone with direct access to your machine to collect this information themselves
+ * and then attempt to match it all together with our collected telemetry data, however most users'
+ * systems are probably not uniquely identifiable via their system info alone.
+ *
+ * ~~~
+ *
+ * Q: I don't want Astro to collect system info. How can I disable it?
+ *
+ * A: You can disable telemetry completely at any time by running `astro telemetry disable`. There is
+ * currently no way to disable this otherwise while keeping the rest of telemetry enabled.
