赤陶暖调

You are designing in Terracotta style inspired by Mediterranean clay craftsmanship.
- Use warm earth tones: cream #faf5ef, terracotta #b5654a, sand #d4a373, earth #7a6350
- Accent with olive green #8b9d77 for natural vitality
- Rounded corners (rounded-lg, rounded-xl) to evoke handcrafted ceramics
- Warm, soft shadows using terracotta-tinted shadow colors
- Generous spacing for a relaxed, inviting feel
- No cool blues, purples, or neon colors
- No sharp corners or heavy black elements
- Font weights: medium and semibold for headings, regular for body
- Think sun-baked clay, olive groves, and warm Mediterranean light

## Animation & Interaction Rules

- Sun-Baked Glow: 悬停时使用暖色光晕与背景加深，模拟陶土被阳光加热后的温润光感。
- Clay Press: active 禁止弹性缩放，使用 translate-y 与 inset shadow 呈现坚硬材质下压阻力。
- Handcrafted Slowness: 交互使用 duration-300 ease-out，避免现代感过强的弹跳反馈。
- Earthy Focus: 表单 focus 以赤陶或橄榄绿边框强化状态，避免刺眼蓝色外圈。
