Derived Play: Motion Cue Karaoke

Create one polished public-gallery concept image titled exactly "Derived Play: Motion Cue Karaoke".

Output format: one vertical 9:16 mobile challenge screen / playful workflow poster, not a physical board game, not a tabletop photograph, not a macro object, not a contact sheet. It should look like a usable fictional creative challenge interface where players sing/call out motion cues over a generated still.

Scene: a fictional mobile app screen for a group prompt game. The top shows an invented still frame named "Moonlit Ferry" with a tiny ferry silhouette on an imaginary lagoon. Below it, three stacked cue lanes act like karaoke lyric tracks: "Camera", "Subject", "World". A moving playhead crosses timestamps and players fill short cue cards to keep the scene consistent.

Exact short readable text to render: "Derived Play: Motion Cue Karaoke", "Moonlit Ferry", "Camera", "Subject", "World", "pan right", "drift slowly", "lantern ripples", "00:01", "00:03", "00:05", "Match 8/10", "Conflict fixed", "Next cue". Keep text short and legible; do not add long paragraphs or random text.

Mechanism: derived playful rules from the Motion Handoff Deck. Players take turns adding motion cues in the correct lane; the visual rewards consistent timing, visible camera direction, subject continuity, and conflict repair. Show a score meter, a small conflict chip, colored cue blocks, and a final preview thumbnail. Make it clearly about prompt mechanics, not about real video generation output.

Visual style: vibrant but restrained mobile UI, crisp accessible typography, dark graphite interface, teal lagoon preview, amber cue highlights, coral accent for conflict chip, soft glow only where UI needs emphasis, polished product prototype quality. Use icons for playhead, camera, ferry, wave, and checkmark. No purple-dominant palette, no brand logos, no watermark.

Safety and rights: all fictional, no real brands or trademarks, no public figures, no politics, no dangerous instructions, no adult or explicit content, no gore or violence, no copyrighted characters, no living-artist style imitation, no source image reuse.
