Prompt
One continuous flat drawing with solid fills that counterchange across a divided background, light and dark reversing at the field boundary and never in the figures, no gradients or texture. An adult at a training briefing in a wide frame: a fictional adult man instructor in his fifties in a plain khaki uniform pointing with an open hand at a plain blank map board in front of a row of seated adult trainees seen from behind, in a bare classroom.
Light: flat solid fills in khaki, deep navy and cream with the background split into a pale half and a dark half and the figures reversed across the boundary, a clean flat drawing with no gradient; palette of khaki, navy, cream and brick; crisp, orderly, graphic.
Wide 16:9 frame. Fictional adult service members only, in plain generic uniforms with no real insignia, flags, names or readable text; no weapons, no combat or violence, no minors, dignified and calm.
