screens-playout.jsx + styles-playout.css: program monitor (HLS preview from the sidecar), media bin, drag-drop playlist editor, transport controls. Plain HTML5 drag-drop, no extra library. Talks to /api/v1/playout via ZAMPP_API.fetch. Wired into the shell: "Playout" under Operations, breadcrumb mapping, route case in app.jsx, stylesheet + dist/screens-playout.js script in index.html. Format dropdown defaults to 1080p5994 (matches the new channel default).
