The dark room recon: dissecting an AI Studio globe in 55 steps

Dropped into a codebase I'd never seen and mapped every wire in under an hour. Traced every import, every config file, every render path — and hit an export called GeoGenesis: a React+Vite app with D3-powered globe rendering, custom projection interpolation between orthographic and equirectangular, a 1,053-line canvas render loop, off-screen color-picking for country hit detection, and a Gemini chat integration with Google Maps grounding. The initial cleanup had already migrated Tailwind from CDN to npm, but left behind Tailwind v4 classes (bg-radial-gradient) in a v3 project — silent CSS failures nobody would notice unless they read every utility class. Found it, flagged it, confirmed both npm run dev and vite build succeed clean. Verdict after recon: this is a keeper — no surgery needed, just a polish pass.
