Fix: Code block overflow on mobile in N/M Base docs using responsive grid

[arty0928]

Resolves #475

Problem: Code block layout overflow on mobile devices in N/M Base documentation

The code examples in the N/M Base documentation page were displayed using a fixed 2-column grid layout (gridTemplateColumns: '1fr 1fr'), causing horizontal overflow and breaking the layout on mobile devices.

Root Cause

The N/M Base documentation page used a fixed 2-column grid layout that caused horizontal overflow on mobile devices.

// apps/landing/src/app/(detail)/docs/core-concepts/nm-base/page.mdx
<div
  style={{
    display: 'grid',
    gridTemplateColumns: '1fr 1fr',  // Fixed 2 columns
    gap: '2rem',
    marginBottom: '2rem',
    alignItems: 'start',
  }}
>

Solution: Implemented dedicated ExampleGrid component for MDX

Background:

While DevupUI's Grid component supports responsive arrays, it cannot be used directly in MDX files because the MDX parser (acorn) cannot parse array syntax within JSX:

<!--  MDX parsing error -->
<Grid gridTemplateColumns={['repeat(1, 1fr)', 'repeat(2, 1fr)']}>
  <div>A</div>
  <div>B</div>
</Grid>

Solution:

Created a separate .tsx component to be processed by DevupUI's compiler at build time:

// ExampleGrid.tsx - compiled at build time
export function ExampleGrid({ children }: { children: ReactNode }) {
  return (
    <Grid 
      gap="16px" 
      gridTemplateColumns={['repeat(1, 1fr)', 'repeat(2, 1fr)']}
    >
      {children}
    </Grid>
  )
}

Design decisions:

• Reuses DevupUI's Grid component for consistency with existing codebase
• Uses responsive array pattern following DevupUI standards
• children: ReactNode type for flexible number of child elements
• Server component optimized at build time

Result

Before	After
20251031-0540-55.3463390.mp4 ❌ Fixed 2-column grid causes horizontal overflow and content cut off ❌ Users must scroll horizontally to view code examples	✅ Responsive grid: 1 column on mobile, 2 columns on desktop ✅ All content visible and properly laid out within viewport
