[mergennachin]

Code Quality Improvements

• Fixed HTML syntax error: Corrected invalid closing tag ( → ) on line 1179
• Removed duplicate code: Eliminated ~80 lines of duplicate CSS definitions and redundant JavaScript event handlers
• Fixed JavaScript event handling: Added explicit event parameter to all switcher functions (switchBackend, switchPlatform,
  switchMultimodalPlatform) and updated all 11 onclick handlers for better browser compatibility

Architecture Improvements

• Externalized CSS: Moved ~1000 lines of inline CSS to separate style.css file, reducing HTML from ~2107 to ~1070 lines
• Removed deployment artifacts: Removed hardcoded Cloudflare analytics script that should be injected at deployment time

Design Consistency

• Standardized section padding: Unified all section padding to 5rem 0 (except Hero at 7rem 0 4rem and Footer at 3rem 0)

Marketing Updates

• Updated backend names to marketing-approved branding:
  • XNNPACK with Arm Kleidi
  • Qualcomm® AI Engine for Qualcomm® Hexagon™ NPU
  • Apple Core ML for Apple silicon
  • NXP Semiconductors' eIQ® Neutron NPU
  • Apple Metal Performance Shaders (MPS)
  • OpenVINO from Intel
  • Samsung Exynos NPU
  • Arm Ethos-U NPU
  • and others
