Debugging a Live Content Rendering Bug

The Failure Mode

The bug looked cosmetic at first: content rendered correctly in development but drifted in production. That is usually a signal that some build-time assumption is leaking into runtime behavior.

What Helped

• Reproducing the problem with the smallest possible content file.
• Comparing build output rather than only comparing visible UI.
• Eliminating layers until only the content transform remained.

Takeaway

Many content bugs are not really about content. They are mismatches between where data is transformed, where it is cached, and what the page assumes will still be true later.
