Describe the Bug

Thank you for providing an awesome Astro theme.

I've encountered an issue where specifying a canonical tag in the frontmatter.head results in two canonical tag specifications in the HTML output.

This duplication of canonical tags can potentially cause confusion for search engines and impact SEO performance.

Steps to reproduce:

  • Add a canonical tag specification in head field of frontmatter
  • npm run dev or npm run build
  • Inspect the resulting HTML

Expected behavior:
Only one canonical tag should be present in the HTML output.

Actual behavior:
Two canonical tags are present in the HTML output:

  • One from the frontmatter.head specification
  • Another potentially generated by the system

Possible solutions:

  • Implement a check to prevent duplicate canonical tags
