When adding Material UI components to a Backstage plugin page, what is the primary reason to use Backstage's own components (like `@backstage/core-components`) alongside Material UI?

To ensure visual consistency with the rest of the Backstage application

To avoid using Material UI entirely

To improve the performance of the plugin

To enable server-side rendering

A Backstage plugin developer wants to customize the primary color used by Material UI buttons in their plugin to match their company brand. Which approach directly modifies the Material UI theme to achieve this?

Use the sx prop on each Button to set the color

Override the Button component's className with a global CSS rule

Create a custom theme object with a modified palette and pass it to ThemeProvider

Edit the Backstage app's global CSS variables

A developer is creating a custom component for a Backstage plugin that needs to display a list of items with icons. The developer wants to ensure the component uses the same typography and spacing as the rest of Backstage. What is the best practice?

Use raw Material UI components and manually apply spacing and typography via the sx prop on each element.

Use Backstage's core components (e.g., List, ListItem, ListItemIcon, ListItemText) from '@backstage/core-components'.

Use HTML ul and li elements with custom CSS classes defined in the plugin's stylesheet.

Use Material UI's Table component to display the list, as it provides built-in row and cell styling.

A Backstage plugin developer is integrating a third-party React component library that uses its own styling system. The developer wants the third-party components to appear consistent with Backstage's Material UI theme. The third-party library does not use MUI. What is the most effective way to achieve visual consistency?

Fork the third-party library and rewrite its components using MUI.

Use the useTheme hook to read Backstage's theme values and pass them as CSS variables or props to the third-party components.

Use CSS to override the third-party library's styles to match Backstage's default colors.

Wrap the third-party components in a MUI ThemeProvider and hope they pick up the theme.

A Backstage plugin developer wants to create a layout where two sections appear side by side on wide screens and stack vertically on narrow screens. Which Material UI components and features are designed to implement this responsive behavior?

Grid with breakpoint props like md and xs
