subject: >
  Create a 21:6 wide banner using the provided reference image content.
  The primary face must be centered inside an invisible safe zone (not drawn),
  and a title logo (derived from title_text + title_style_preset) must be placed inside the same safe zone.

composition: >
  Aspect ratio 21:6.
  Invisible safe zone (DO NOT draw it):
  - Left margin: 15% of width
  - Right margin: 15% of width
  - Top margin: 16% of height
  - Bottom margin: 16% of height
  Keep the entire face AND the entire title logo fully inside this safe zone.
  Background may extend to the edges.

  Place the reference image content with maximum fidelity.
  Auto-crop/scale/reposition to fit a 21:6 banner with no stretching.
  Detect the primary face (if multiple faces, pick the largest/most prominent).
  Center the primary face within the safe zone both horizontally and vertically.
  Never crop off the face/eyes; keep the full face comfortably inside the safe zone (not near edges).

  Face zoom behavior:
  - If face_zoom is OFF: keep the original framing as much as possible while still centering the face in the safe zone.
  - If face_zoom is ON: zoom/crop to a bust-up portrait centered on the face

一组冷静、高质感的产品摄影画面。

画面主体是一瓶高端营养补充剂，瓶身完整、干净，密封防拆封条仍然保留，整体呈现出高度精密、被严格控制的工业产品状态。产品被放置在一块哑光石材表面上，石材质地粗粝、自然、略显陈旧，与产品的精致形成对比。

画面中出现明显的“功能错位”细节：在营养补充剂瓶旁，摆放着一把比例明显不合理的{argument name="迷你道具" default="迷你躺椅"}，像是为人休息而准备，却无法真正使用，只是象征性地存在。同时，瓶身或附近贴有一张醒目的警示标签，文字理性、冷淡，却无法明确说明风险来自哪里。

整体构图采用正面居中方式，画面稳定、克制，没有戏剧化角度，强调产品本身的存在感与材质细节。使用柔和但具有方向性的棚拍光线，清晰呈现瓶身的反光、标签纸张的质感、防拆封条的细节，以及石材表面的微小纹理。
