It's nano banana - I actually noticed the same thing. I didn't prompt it as such.

Here's the prompt I used, actually:

Create a vibrant, visually dynamic horizontal infographic showing the spectrum of AI developer tools, titled "The Shift Left"

Layout: 5 distinct zones flowing RIGHT TO LEFT as a journey/progression. Use creative visual metaphors — perhaps a road, river, pipeline, or abstract flowing shapes connecting the stages. Each zone should feel like its own world but connected to the others.

Zones (LEFT to RIGHT):

1. "Specs" (leftmost) - Kiro logo, VibeScaffold logo, GitHub Spec Kit logo

   Label: "Requirements → Design → Tasks"

   Label: "Parallel agents, fire & forget"

   Label: "Autonomous multi-file edits"

   Label: "Inline suggestions"

   Label: "Read & write files"

Aspect ratio: 16:9 landscape
