STRICT ADHERENCE REQUIRED:
  - Follow this YAML specification precisely. Do NOT deviate, add unauthorized elements, or make 'creative' interpretations.
  - Character identity consistency from reference images (if provided) is PARAMOUNT.
  - Thorough image analysis is mandatory to maintain this consistency. Any result that fails character identity checks is unacceptable.

resolution: "{resolution}"    # Change as needed (e.g., "4K")
Character_Count: {{ Total number of characters appearing }}
Total_Panel_Count: {{ Total number of panels (usually 4-8 for a 4-tier structure) }}

Style_Guide:
  # Panel division style is fixed to "no outer frame, display to canvas edge"

  background_elements: "{{ Main setting, specific description of the location, important props or environmental elements placed. }}"
  dialogue_bubbles: "Standard white bubbles for speech, thought clouds for internal thoughts, dashed bubbles for whispers, and rectangular boxes for narration/monologue. {{ Add definitions for special speech bubbles if necessary (e.g., spiky bubbles for shouting) }}"
  visual_effects: "{{ Specify manga visual effects. Manga symbols (sweat, veins, sparkle), effect lines (concentration lines, speed lines, tremor lines), visualization of sound effects, etc. }}"

Characters:
  # Character definition. Alphanumeric IDs recommended.

    description: "{{ Second character details... Describe for the number of characters. }}"
  # Add as needed...
