Pre-merge checks and finishing touches

❌ Failed checks (2 warnings)

Check name	Status	Explanation	Resolution
Description Check	⚠️ Warning	The PR body includes the repository template comment and a PR-Codex overview that summarizes the deprecation banner, deadline, and migration instructions, but it does not populate the required template sections "Notes for the reviewer" and "How to test" nor does it include an issue tag or explicit testing steps. Because those template sections are missing and no concrete test instructions are provided, the description does not meet the repository's template requirements. This prevents reviewers from easily validating behavior and testing the change.	Populate the repository template in the PR body: add the formatted title line and issue tag if applicable, add a "Notes for the reviewer" section describing the banner behavior, deadline, and relevant links, and add a "How to test" section with concrete manual verification steps and any test commands. Include the deprecation date and the dashboard/thirdweb AI links referenced in the PR-Codex to make validation straightforward. After adding these items the description will meet the template and facilitate reviewer validation.
Docstring Coverage	⚠️ Warning	Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%.	You can run @coderabbitai generate docstrings to improve docstring coverage.

✅ Passed checks (1 passed)

Check name	Status	Explanation
Title Check	✅ Passed	The title "[Nebula] Add deprecation banner with migration information" succinctly and accurately summarizes the primary change — adding a deprecation/migration banner to the Nebula login page (NebulaLoginPage). It is concise, uses the bracketed scope prefix, and highlights the main user-facing change without extraneous details. Therefore it meets the repository's expectations for a clear, scan-friendly PR title.
