    Add to this scene: 11 to 15 tourists with a prominent guide.
    
    # PERSPECTIVE & SCALE — non-negotiable
    Before placing any figure, inspect the scene for reference objects and calibrate scale:
    - Find at least TWO scale anchors visible in the input: cars (~1.5 m tall), doorways (~2.0 m), windows (~1.5 m tall), railings/bollards (~1.0 m), street lamps (~4 m), standard bricks (~7 cm tall), standard steps (~15 cm rise). If no usable anchors are visible → return input unchanged.
    - Adult height target: 1.65–1.80 m. Head reaches ~80% of a car roof at same depth.
    - Figures at different depths must scale-down by the SAME ratio as existing scene elements at that depth. Back row figures (further away) MUST be smaller per perspective, not uniformly — do NOT stamp identical-sized figures across rows.
    - Feet MUST touch a visible existing ground surface — no floating, no clipping through floor. Cast ground-contact shadow consistent with existing scene shadows.
    - Shadow direction, length, and softness match the strongest existing shadow within ±10°.
    - Existing railings, bollards, benches, curbs in scene must remain at correct scale — NEVER miniaturize them to "fit" the added group.
    
    # COMPOSITION
    - Guide prominent, slightly elevated or front-center, facing the group.
    - Mixed demographics (ages 25–60, varied ethnicities), some with small backpacks.
    - Group occupies about 40% of frame width in a clearly organized formation.
    - If the scene has DEEP perspective: arrange in 2 rows (front row ~6–8 people, back row ~5–7 smaller per perspective).
    - If the scene is SHALLOW or telephoto (flat depth): arrange in single wider row to keep everyone visible, proportion-consistent.
    
    # REJECTION CONDITIONS
    If any of the following, return the input unchanged:
    - No open area accommodating 11–15 figures without crowding main subject.
    - Only one or zero scale anchors visible — cannot calibrate reliably.
    - Scene is tight close-up, aerial top-down, or pure texture.
    - Scale calibration would require figures smaller than 60% or larger than 140% of calibrated adult height.
    
    Match scene lighting and shadow characteristics precisely. Main subject fully visible beside or behind the group.
