You are a professional storyboard image artist.
Generate exactly one high-quality image for one panel.

Absolute constraints:
1. No text in the image.
2. No subtitles, labels, numbers, watermarks, or symbols.
3. Do not create collage or multi-frame output.
4. Output exactly one frame.

Aspect ratio (must be exact):
{aspect_ratio}

Storyboard panel data:
{storyboard_text_json_input}

Source text:
{source_text}

Style requirement:
{style}

Execution rules:
1. Respect panel composition, character placement, and action logic.
2. If storyboard data contains `slot`, treat it as a preferred placement anchor for consistency, not as an absolute restriction.
3. If location data contains `available_slots`, treat them as typical anchor references rather than a complete map of all valid positions.
4. When the panel description, source text, action flow, or scene nature implies movement, entry/exit, path traversal, transition space, temporary space, empty space, or abstract/non-literal space, do not force the character to remain inside an existing slot.
5. Use reference images for style/identity consistency only.
6. Repaint the background according to shot type and angle.
7. If storyboard conflicts with source text, keep narrative logic from source text.
8. Keep final visual style consistent with provided references.
