IMAGE TYPE
Polished mobile-game gameplay reference frame, opaque PNG, portrait 9:16.

SUBJECT AND SCENE
Layerline, a calm flat 2D logic game. A centered deep-navy board well contains six overlapping thin
matte enamel circuit shutters. Each shutter is a rounded rectangle hinged by one integrated pill tab.
Show one shutter midway through a flat edge-axis flip. The current shutter face has one dark ink
trace; the alternate face has a different trace. The flip visibly exposes one shutter while covering
part of another. One mint source and two amber geometric terminals are on the board. Show one current
mint powered route and one clearly separate dashed blue prospective route caused by the flip.

COMPOSITION AND CAMERA
Orthographic front view, no perspective, no room or device mockup. Board uses about 74 percent of
safe portrait width. Large readable objects, generous negative space, shallow separation shadows.
Minimal real gameplay UI: small level label at top, undo, restart, and pause controls outside the
board. Make the dual consequence understandable at thumbnail size.

VISUAL STYLE
Premium calm vector-like 2D mobile-game art, precise rounded geometry, soft but not childish,
distinctive editorial instrument-panel design. Not photoreal, not a presentation board.

LIGHTING AND COLOR
Flat ambient lighting with shallow contact shadows. Background #101522, board well #182033,
primary shutters #D9E3EE, alternate shutters #7F90A8, unpowered traces #263148, live power #63E2C2,
terminals #FFC45C, preview #73B7FF, labels #F4F7FA. Powered state also uses thicker line and soft halo.

MATERIALS
Opaque matte enamel or polymer. Clean edges. No texture noise, paper grain, glass, metal grime, wood,
or fabric.

TEXT
Only the small readable label "1-3". No other words, captions, logos, badges, prices, or watermarks.

CONSTRAINTS
Exactly one coherent playable board. Hinges are tabs, never screws, bolts, rivets, or pins. No
origami, paper fold picture, independent pipe-tile grid, tray sorting, removed pieces, botanical
objects, characters, coins, stars, loot, cyberpunk neon, dense PCB detail, isometric view, 3D camera,
fake app-store UI, or illegible decorative text. The preview must not look like a second committed
power state. Preserve safe margins.
