All components now render properly on mobile devices without:
- Horizontal overflow
- Text too large for viewport
- Buttons/tabs too small to tap
- Excessive padding wasting screen space

Added comprehensive 360px breakpoint across all components to prevent horizontal scrolling on the smallest mobile devices:

**Landing Page (index.module.css:232-280):**
- Added 360px breakpoint with aggressive size/padding reduction
- Reduced hero padding to 1.25rem 0.5rem (8px sides)
- Scaled down title to 1.75rem with word-break for wrapping
- Reduced all gaps and spacing throughout
- Smaller buttons (0.9rem font, reduced padding)
- Compact badges (16px height, 0.375rem gap)

**HeroCodePreview (styles.module.css:140-179):**
- Limited preview width to calc(100vw - 1rem) to prevent overflow
- Added word-break and pre-wrap to force code wrapping
- Ultra-compact terminal (8px buttons, 0.65rem title font)
- Reduced code font to 0.75rem with horizontal scroll fallback
- Applied wrapping to both pre and code elements

**CodeShowcase (styles.module.css:222-290):**
- Added overflow: hidden to tab container
- Made tabs flex with min-width: 0 to prevent expansion
- Ultra-compact tabs (0.7rem font, 0.5rem padding)
- Text-overflow ellipsis on code block headers
- Reduced code blocks to 0.7rem font with proper overflow handling
- Ensured all containers respect viewport boundaries

**FeatureGrid (styles.module.css:191-238):**
- Reduced section padding to 1.5rem 0.5rem
- Compact feature cards (1rem padding)
- Smaller icons (2rem) and fonts throughout
- Code blocks: 0.65rem font with horizontal scroll
- Improved line-height for better readability on small text

**QuickStartSteps (styles.module.css:257-327):**
- Compact step numbers (40px) and content
- Ultra-small copy button (0.65rem font)
- Reduced all padding and gaps
- Code blocks: 0.7rem font with overflow-x auto
- Smaller CTA buttons (0.9rem font)

**GitHubStats (styles.module.css:67-84):**
- Added 360px breakpoint
- Reduced stats to 1.125rem font
- Ultra-compact labels (0.6rem)
- Minimal gaps (0.5rem)

All changes ensure no horizontal scrolling occurs on devices as small as 320px width while maintaining readability and usability.
