Commands or code

I can start with a diagnostic pass for the hydration error.

To scope it properly, I need:
- the exact page or preview link
- the full console error screenshot
- reproduction steps
- repository access or a minimal reproduction
- permission to work on a test branch or PR
- the expected acceptance criteria

This diagnostic pass will identify the likely cause and recommended fix. I will confirm the final implementation scope after reviewing the project context.

Risk notes

Confirm the real project environment, account permissions, platform rules, and output quality before delivery. Do not ship AI-generated changes without human review, and do not claim indexing, income, deployment success, or ranking improvements without measured evidence.
