The shop.html.heex and shop_root.html.heex were both full HTML documents.
When nested (root layout + live layout), this created invalid HTML with
duplicate <!DOCTYPE>, <html>, <head>, and <body> tags.
This caused:
- "Cannot bind multiple views to the same DOM element" console errors
- Failed Lighthouse audits
- Potential rendering issues
Fix:
- shop_root.html.heex: Now contains the full HTML document with theme
settings, CSS variables, and data attributes
- shop.html.heex: Now just passes through @inner_content
Results:
- Console errors: Gone
- Best Practices: 96 → 100
- Total Blocking Time: 140ms → 30ms
- HTML validation: Passes
