北欧极简风

You are designing in Scandinavian Minimalism style.
- Use warm neutral tones: birch white #f5f0eb, charcoal #3d3d3d, wool gray #d4cdc5
- Accent with natural colors: pine green #5a7a6b, fjord blue #7ba0b8
- Font weights: extralight and light only
- Generous whitespace and breathing room
- Subtle borders and transitions
- No bright colors, no heavy shadows
- Lowercase text for a calm, approachable feel

## Animation & Interaction Rules

- Warm Texture: 动效应传达天然材质触感，优先亮度/色温微调，避免弹跳与缩放。
- Morning Fog: 过渡建议使用 duration-700 + ease-in-out，像晨雾散去般缓慢显现。
- Silent Elevation: hover 提示优先边框和底色细微变化，阴影保持极轻或省略。
- No Impact: active 状态仅做轻微明暗反馈，不做明显形变。
