Greptile Summary

This PR correctly implements the show_in_cards feature for hiding blog posts from listing surfaces while keeping them routable. The changes are sound and well-distributed across all listing call-sites (blog gallery, navbar, about page news section, and post sidebar). The filtering logic in blog_data_visible() properly excludes posts marked show_in_cards: False while route generation still includes all posts, preserving their accessibility via direct URLs. No functional issues detected.

Confidence Score: 5/5

• Safe to merge with no functional issues identified.
• The implementation is correct and complete. All four listing surfaces properly use blog_data_visible() to filter posts, while hidden posts remain accessible via their direct routes. The feature is properly integrated without breaking existing functionality.
• No files require special attention.

Important Files Changed

Filename	Overview
pcweb/pages/blog/paths.py	Adds blog_data_visible() function that correctly filters posts by the show_in_cards metadata flag. Functional and correct.
pcweb/pages/blog/blog.py	Refactors component_grid() to use blog_data_visible() via list comprehension. Route generation correctly still iterates blog_data, ensuring all posts remain routable.
pcweb/pages/blog/page.py	Uses blog_data_visible() for the "More Posts" sidebar. Hidden posts correctly fall back to showing the first 3 visible posts since they won't be found by title.
pcweb/pages/about/views/news.py	Switches to blog_data_visible() for the "What's New In Reflex" section. Correctly displays up to 3 visible posts.
pcweb/views/marketing_navbar.py	Uses blog_data_visible() in the navbar blog dropdown with proper empty-list handling. Improves safety compared to the original code.
