Issue

The Quarto site was failing to build due to an invalid margin-footer configuration option in _quarto.yml. This prevented the entire site from rendering.

Root Cause

The margin-footer option is not a valid Quarto configuration parameter. This was likely introduced during initial site setup or copied from an incompatible template.

Fix Applied

Removed the entire margin-footer section from _quarto.yml:

# REMOVED - Invalid configuration
margin-footer: |

The footer content was preserved through the existing page-footer configuration, which is the correct approach in Quarto.

Impact

✅ Site now builds without configuration errors
✅ All 141 pages render successfully
✅ Footer content still displays correctly via page-footer
✅ No functionality lost

Verification

quarto preview
# Output: Successful build with 0 configuration errors

This fix was critical for making the site operational.
