name: wai-quantum studio and desktop

# Quantum Studio (wai/quantum-studio), the interface for the browser and the
# desktop, and the desktop app around it (wai/wai-quantum-desktop):
#   - the Studio built against the engine's browser package (wai-web, feature
#     quantum_engine) and run in a browser by test/studio.test.mjs: linted, drawn and
#     planned as it is typed, run here with its receipt checked here, an error marked
#     on its line, any angle on the state vector, Ctrl+Enter, and the program and the
#     history kept across a reload; nothing scrolls sideways at a phone's width;
#   - the desktop app's tests and clippy with warnings as errors, and `check`: a job
#     run in the app's worker process, sealed in the app with a key that never leaves
#     it, and verified, with no window.
