Description:

Page titles currently show duplicate site names (e.g., "About | Site Name | Site Name") because createPageMetadata() unconditionally applies template formatting to already-formatted titles. The fix is to use the raw title parameter when provided, only falling back to the default template for pages without explicit titles.

Tasks:

• Metadata Utility (src/lib/metadata.ts)
  • Replace title: fullTitle with title: title || seoDefaults.defaultTitle in return statement
  • Verify browser tabs display correct, non-duplicate titles across all pages
