Addressed UI stability by refining the Boards component to ensure text ellipsis appears only when content overflows, improving readability in data-heavy dashboards. Updated snapshot tests to align with changes in default date ranges, supporting reliable regression testing. In the authentication flow, simplified user sign-in by removing the Google option and consolidating to Mezon, reducing maintenance and potential security issues.
