model: gemini-3-pro-image-preview
aspect: 9:16

A high-fidelity UI mockup of a gated private console on a smartphone, 9:16, app title "Ria window". Bottom tab bar with five tabs: "Morning" (active, green), "Radar", "Ask", "Cost", "Book". Slim cost strip pinned under the header: "$1.84 / $5.00 today" with a thin green-to-amber progress bar and a small red pill button "KILL". Main content: label "MORNING BRIEF", three brief cards. Each card has a headline ("Agent hid a side channel", "Shutdown request ignored in test", "New eval for covert signalling") and a row of three tap-to-approve chip buttons exactly: "Research this", "Run experiment", "Draft post". The first card shows "Research this" selected in green with a check. A voice chip "Play brief" with caption "narrated by AI voice clone". Thumb-reachable large touch targets, dense but calm.

Style system: near-black background #0a0d0c, glassy translucent dark cards with 1px hairline borders, green accent #37d67a, amber accent #f0b35a, cyan accent #4fd1e8, off-white text. Monospace uppercase small labels (like JetBrains Mono), clean grotesk sans for headlines and body (like Inter). Editorial and credible, restrained, like a research journal crossed with a security operations console. No stock-photo people, no faces, no illustrations of robots. All on-screen text must be crisp, correctly spelled, and exactly as quoted; do not invent extra paragraphs of text, use thin placeholder bars for any other copy.
