AntiVibeCodedFingerprints [fact] v1.0.0

Vibe-coded UIs — built by describing aesthetic feeling to an AI without explicit design constraints — reliably produce a small set of recognizable fingerprints: saturated neon on dark backgrounds, glassmorphism cards, bounce-eased micro-animations, and oversized gradient hero sections.

Vibe-coding produces its own predictable aesthetic: dark background + neon accent (#00FFAA, #FF00FF, or cyan #06B6D4) + frosted glass panels + every card animated with spring-back bounce + hero with radial gradient blob decoration. These are the 'vibe-code fingerprints' distinct from the Inter/purple slop pattern but equally recognizable as undesigned — just undesigned in the 'cool tech startup' direction rather than the 'generic SaaS' direction.

Counter Conditions

• When a persona brief specifies the vibe before coding begins, some vibe-code aesthetics are appropriate (e.g. neon on dark for a gaming product with an editorial brief).
• The problem is not the aesthetic itself but arriving at it through statistical inference rather than design intent.
