Measurement boundaryWhat it exercises What it does not establish
The task emphasizes interface craft and state coordination, not factual knowledge or long-horizon software maintenance.
Frozen brief
The latest published prompt.
Create a one-screen browser instrument called ORBIT RADIO. A large central dial tunes between five fictional deep-space signals. Turning or dragging the dial must change the station name, frequency, color, and an animated signal visualization. Add compact previous/next controls and make the current station unmistakable. Use one self-contained HTML file with vanilla CSS and JavaScript, no external assets or libraries, and make it responsive.
