+## 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
