- Using new Date().toISOString() at build time will set both dateModified and publishDate to whenever the site is built, not when the content actually changes. This means every build will show all pages as "just modified" and "just published" even if their content hasn't changed. Consider either:
- Removing these dates if you don't track actual modification/publication dates
- Implementing a proper content versioning system to track real dates
- Using static dates that represent actual content changes

The Nunito font is being loaded twice: once as a regular stylesheet (lines 21-24) and once via preload (lines 39-44). The preload with the onload trick should replace the regular link, not be added alongside it. Remove the regular stylesheet link at lines 21-24 since the preload mechanism already loads the font.

The Content Security Policy includes 'unsafe-inline' and 'unsafe-eval' in the script-src directive, which significantly weakens security protections against XSS attacks. While these may be needed for analytics and the current implementation, consider:
- Using nonces or hashes for inline scripts instead of 'unsafe-inline'
- Moving away from 'unsafe-eval' by refactoring any code that requires it
- At minimum, document why these are necessary and create a plan to remove them

The samples configuration is set to 1, which provides less accurate results. The plan documentation (plan/ninjatype-seo-implementation.md line 1187) recommends using samples: 3 for better accuracy. Consider increasing this to at least 3 samples to get more reliable Lighthouse scores.

Throttling is disabled (throttle: false), which means the audit won't simulate real-world mobile network conditions. This can result in overly optimistic performance scores that don't reflect actual user experience. Enable throttling to get more realistic performance metrics: throttle: true

The RSS feed references a stylesheet at "/rss/styles.xsl" that doesn't exist in the repository. This will result in a 404 error when RSS readers try to fetch the stylesheet. Either remove the stylesheet reference or create the XSL file to style the RSS feed in browsers.

The aggregate rating values (4.8 rating with 150 reviews) appear to be placeholder or fake data. Including fabricated reviews in structured data violates Google's guidelines and can result in manual penalties. Either remove the aggregateRating field entirely, or only include it if you have legitimate, verifiable reviews from real users.

The pubDate uses "2024-01-01" which is in the past, while the implementation summary documents indicate this work was done in "February 2026" (per implementation-progress.md). Using accurate publication dates is important for RSS feed relevance and SEO. Consider using the actual date when these pages were created or last significantly updated.

The getCollection function is imported but never used. The RSS feed uses static content items instead of dynamic content from collections. Either remove this unused import or implement dynamic content collection if that was the intended design.
