- Hero: linear-gradient(135deg, #f0f4ff → #e8f5e9) replacing plain white
- Cards: --bg-card #fafafa + --border-soft #eaeaea + 12px radius for step/eco/doc-link
- Typography: system font first (Apple/BM > Inter); h1 44/800 → 40/600/-1.5; nav 14/500 → 13/400; step badges → uppercase 'Step N'; cards h3/p/a all -1px / -100~200 weight
- Resources icons: emojis → minimal char glyphs (▹⚙✶?)
- Eco card #2: replace 兼容主流 AI Agent → 场景方案 (Live Translate Demo + HappyHorse Prompts)
