## Additional Fix Implemented The previous implementation was missing the display of rack descriptions in the rack visualization section (RackDiagramSection component). ### Changes Made: - `frontend/src/components/rack-diagram-section.tsx:266-268` - Added rack description display in control mode (main dashboard) - `frontend/src/components/rack-diagram-section.tsx:357-359` - Added rack description display in settings mode ### What was missing: The original issue required: "Display the rack description in an appropriate location in the rack visualization section" While the RackDescriptionEditor component was added to the Settings page for editing descriptions, the descriptions were NOT being displayed in the rack visualization cards (RackDiagramSection) on either the main Control page or the Settings page visualization. ### Verification: - Frontend build: SUCCESS - Frontend tests: 111/111 passed - Backend config API tests: 68/68 passed - Merged to main and pushed to remote ### How to test: 1. Add a description to any rack via Settings > Rack Information 2. Go to the Control page - the rack description should appear below the "42U rack · Drag devices" text 3. Go to Settings > Rack Visualization section - the description should appear below the rack info
