# Build: "Sideband" — a one-screen portfolio you tune like a radio

## 0. Brief

A portfolio for a fictional product designer and creative developer, Mara Okon (Lisbon). The page never scrolls. The wheel, a swipe, a drag on the dial or the arrow keys move a needle across an FM band (87.5–108 MHz) with nine stations: Index, six projects, About and Contact. Each station is a full-bleed cinematic photograph and has its own synthesized sound; between stations the picture tears into film grain and static, and the receiver hisses and whistles until the needle locks. Type: a regular-weight grotesk under a giant dot-matrix frequency readout; one amber lamp marks the needle. A template: all content lives in one module.

The full prompt unlocks at launch.
