Fly.io is the edge-cloud platform that runs full-stack apps in regions close to users. Its identity is a high-contrast pact: saturated Fly-purple `#5C58F0` punching out of deep-black surfaces, modernist Inter and Söhne sans-serif, and monospace code blocks that read like terminal output.

The visual language stays disciplined: no rainbow accents, no light-mode default, no decorative serifs. A world map dotted with region markers, sharp-edge cards, and purple-tinted shadows do all the talking — every element earns its place in the developer-cloud composition.
