Metro Doodle Snapshot Diary

Style anchors

• Preserve the core visual identity: A handheld urban transit photo-collage style combining realistic crowded metro, bus, tram, or station snapshots with expressive marker-like cartoon doodles, oversized foreground gestures, white handwritten diary notes, and saturated comic face overlays.
• Use BACKGROUND_ELEMENTS to control secondary scene details, textures, signage, props, and environmental cues.
• Use a realistic candid phone-photo as the base layer.
• The scene should feel like a real public transit or dense city moment: visible doors, rails, signs, floor markings, lights, scuffed surfaces, reflections, crowd density, practical clothing, and imperfect handheld framing.
• Draw playful comic-marker doodles directly on top of the photo.
• Place loose white handwritten diary text in natural negative space, usually near the upper-left.
• Avoid watermarks, usernames, platform logos, creator IDs, app marks, QR codes, clean vector-only illustration, fully illustrated backgrounds, polished ad layout, empty transit scenes, luxury lighting, perfect symmetry, branded mascots, identifiable celebrities, and tiny unreadable text.
• Keep the same visual genre, density level, and rendering mode across new subjects.

Do

• Replace subjects, props, locations, text, and story details through examples.values.
• Keep prompt_template placeholders declared in environment_variables.
• Preserve the style_fidelity_anchors when adapting the JSON to a new image request.
• Use short, readable text values for MAIN_TEXT and SECONDARY_TEXT.
