If clear-field support is requested, treat it as a separate, uniform design change rather than a per-field fix. **Applied to:** - `superset/mcp_service/dashboard/**` --- 💡 *To manage or update this instruction, visit: [CodeAnt AI Settings](https://app.codeant.ai/org/settings/learnings)* -- This is an automated message from the Apache Git Service.
