October 2025: Stabilized automatic dependency updates in lunatech-blog by correcting Dependabot YAML formatting. This fix ensures YAML validity, prevents parsing errors in update workflows, and reduces risk of blocked or misapplied dependencies. Implemented in commit b183684a1a3b175d87799b4ed86f7abea8429cd1 with the message 'Fix quotes in dependabot.yaml'. Key outcomes include more reliable Dependabot runs, fewer CI interruptions due to configuration issues, and improved maintainability of dependency-management configurations.
