水墨画风

You are designing in Ink Wash (Chinese ink painting) style.
- Warm xuan-paper backgrounds: #f8f5f0, #f3efe8
- Ink-black text color: #2c2c2c
- Muted natural accents: moss green #6b7b6e, tea brown #a89279, sand #c4b9a8
- Always use serif fonts (font-serif) for calligraphic feel
- Extreme whitespace: py-32, large gaps between sections for "qi" flow
- Ultra-thin ink borders: border-[#2c2c2c]/20
- Slow transitions: duration-700 to mimic ink diffusion
- No bright saturated colors, no heavy shadows, no decorative elements
- Embrace generous emptiness -- whitespace IS the design
- Think "ink on xuan paper" and "mountain mist landscape"

## Animation & Interaction Rules

- Ink Bleed: 悬停时使用颜色渐深和微弱扩散阴影，模拟墨迹晕染，不做明显位移。
- Calligraphic Press: active 状态优先使用深色内阴影，模拟落笔压纸，不使用机械缩放。
- Flow of Qi: 交互节奏使用 duration-700 到 1000，配合 ease-in-out 保持空灵呼吸感。
- Whispering Text: 文本可从低对比缓慢过渡到清晰墨色，避免跳变式强化。
