/* ============================================================
   伍壹零 · 设计系统 v5 — 浅色 AI 科技风
   浅色基底 + 白卡片 + 高对比排版 + 克制动效
   对标 Stripe / Linear (light) / Vercel 的质感密度
   变更要点（v4 → v5）：
   - 全面切换浅色系；页脚 / CTA / 计算结果面板保留深色作为视觉锚点
   - h1/h2 加 text-wrap:balance，从根源避免标题单字孤行
   - section__head 加宽至 860px，标题字号微调，减少尴尬换行
