Extremely subtle static ring (1px border) with a sharp, minimal drop shadow that appears instantly on hover. Conveys technical snappiness and zero latency.
CSS Math Analysis
Implement a Vercel-style card hover effect. Cards should default to having no shadow, only a subtle 1px border. On hover, apply a quick 150ms transition that introduces a minimal drop shadow (0 4px 6px -1px rgba(0,0,0,0.05)) and slightly darkens the border, without scaling the card geometry. Keep it snappy and highly responsive.
