src/views/ModelSelectionDialog.tsx:314

• The error message color is hardcoded. Use a theme color instead for consistency. For example, use color="error".

<Typography variant="caption" color="#c82c2c">

src/views/DataView.tsx:113

• Using a hardcoded color value is not recommended. It should use the theme's color system for consistency. Replace color="#1770c7" with color="primary".

color="#1770c7" onClick={()=>{ dispatch(dfActions.setFocusedTable(t.id)) }}
