- Changed AgentHeroAlt and Homepod description text from text-gray-800 to text-gray-600 for softer contrast
- Added vertical translation to animation SVGs: NoCentral (-translate-y-10), DataControl (-translate-y-12), Security (translate-y-6), Resilience (translate-y-5)
- Updated Resilience and Security danger color from red (#ff4d4d) to gray (#9ca3af)
- Changed NodeBenefits card border from border-gray-300
