  "prompt": "This workspace is a freshly scaffolded Native SDK native-frontend app (see README.md; the view is src/app.native, the logic src/main.zig). Replace the counter with a small playlist queue pane.\n\nRequirements:\n- A queue list rendered from model data, seeded with exactly three tracks displayed as exactly \"Golden Hour\", \"Night Drive\", and \"Morning Rain\" — one selectable row per track, each row reading as its track title to assistive tech.\n- Clicking a row selects it. Selection is model state, exactly one row is selected at a time, the selected row must read as selected to assistive tech, and \"Golden Hour\" starts selected.\n- Playing is model state only (no audio): pressing plain Enter on a keyboard-focused row starts playing THAT row's track — the row's PRIMARY action, distinct from selecting it. Wire this through the row itself so the keyboard activation carries the row's own identity in its message payload; do not reconstruct the target from the selection, and do not add a window-wide Enter mapping for it. The toolkit's list rows have a first-class channel for a row's primary action — use it.\n- Keys no focused widget claims must still work app-wide: with nothing focused (before any Tab), Space starts playing the selected track when nothing is playing and stops playback when something is, and ArrowDown/ArrowUp move the selection down/up, clamping at the ends (never wrapping). The toolkit has a first-class app-level seam for keys no focused widget consumes — use it; do not fake it with focus tricks or press handlers on layout elements, and leave keys the app does not own unclaimed.\n- A status bar reading exactly \"Selected: <selected title> · Playing: <playing title>\" (with that middle dot), where <playing title> is exactly \"none\" whenever nothing is playing, updating live. Derive it; do not store it.\n- Keep all logic in src/main.zig (Model, Msg, update); the markup only binds values and dispatches messages.\n- Validate the markup with `native markup check src/app.native`, and keep `zig build test` green — extend src/tests.zig so the tests: drive a row's keyboard activation through the real dispatch path (the finalized tree's keyboard channel), asserting that Enter on a row dispatches that row's play message and Space on the same row dispatches its select; exercise the app-level key mapping directly, asserting Space and both arrows map to the right messages and a key the app does not own maps to nothing; and assert through update that the selection clamps at both ends and that Space's play/stop toggle round-trips.\n\nWhen you are done, make sure `zig build test` passes and summarize what you built.",

        "Tests are meaningful: they drive Enter and Space on a row through the finalized tree's keyboard channel asserting the two distinct messages, exercise the fallback mapping directly including a key it does not own, and assert selection clamping at both ends plus the play/stop round-trip through update — not merely that the code compiles.",
