Poem

🐰 A patch, so small, yet swift and neat,
Fifteen five nine makes the journey complete,
No features changed, no bugs to squash,
Just dependencies—whoosh—a gentle refresh!
Onward we hop, steadily up the version tree. 🌲

package.json (1)

21-21: Missing lock file: The repository should include a yarn.lock file (based on .gitignore configuration indicating Yarn usage), but it is absent. This prevents reproducible builds and consistent dependency resolution across environments and CI pipelines.

The Next.js version bump itself (15.5.7 → 15.5.9) is a safe patch-level update. However, before merging this dependency change, ensure that the yarn.lock file is generated and committed to the repository. This is critical for maintaining build reproducibility across all team members and CI/CD systems.
