## Definition
|
||
|
||
Style Lock（风格锁定块）是 AI 图片生成质量控制机制——在每个提示词末尾加强制的风格比对检查清单，要求在生成前逐项验证与上一张图片的风格参数是否完全匹配，偏差即触发重生成。
|
||
|
||
## Mechanism
|
||
|
||
Style Lock 通过以下方式工作：
|
||
|
||
1. **复制前一张图片的完整 Style Seed**
|
||
2. **添加逐项检查清单**（Checklist），要求生成前验证每个风格参数
|
||
3. **强化约束指令**：If ANY element does not match, regenerate with corrections
|
||
4. **视觉反馈**：通过 hex 色值、纹理描述、线条质量等具体参数减少模糊性
|
||
|
||
## Sample Template
|
||
|
||
```markdown
|
||
== STYLE LOCK — MANDATORY ==
|
||
|
||
This card MUST follow the EXACT same chalkboard style as the
|
||
previously generated card. Do not deviate.
|
||
|
||
Checklist — verify these match the previous card BEFORE generating:
|
||
□ Background color: #1C2B1C (dark green-black chalkboard)
|
||
□ Chalk texture: subtle scratches, dust, eraser smudges
|
||
□ Line quality: hand-drawn, imperfect, sketchy wobble — NO perfect vectors
|
||
□ Color hex values: #F5F5F5 (white), #FFE566 (yellow), ...
|
||
□ Frame: wooden border with hand-drawn wood grain
|
||
□ Doodles: stars, underlines, arrows, circles — all chalk-drawn
|
||
□ Typography: chalk lettering, imperfect baseline
|
||
|
||
If ANY element does not match, regenerate with corrections.
|
||
```
|
||
|
||
## Consistency Rating
|
||
|
||
| Method | Consistency | Complexity |
|
||
|--------|-------------|------------|
|
||
| Style Seed only | ★★★★☆ | Low |
|
||
| Style Seed + Style Lock | ★★★★★ | Medium-High |
|
||
| Reference Image + Style Lock | ★★★★★ | Medium |
|
||
| All methods combined | ★★★★★ | Medium-High |
|
||
|
||
## Relationship to Style Seed
|
||
|
||
- [[StyleSeed]]：定义风格参数（正面锚定）
|
||
- [[StyleLock]]：强制比对上一张参数（反向验证）
|
||
- 两者组合使用：开头用 Style Seed 锚定正面目标，末尾用 Style Lock 验证反面偏差
