/* ==================================================================
   菲 FAYE · 王菲的歌声 — 视觉系统 v3（重构版）
   依据 ai-design-skills / landing-page-design：
   · 字号对齐 Tailwind 字阶；间距走令牌 8/12/16/24/32/40/48/64/96
   · 深色底只用 #000000 #181818 #1F1F1F #272727；背景平铺不用渐变
   · 动效统一 cubic-bezier(.22,1,.36,1)，最短 200ms，只动 transform/opacity
   · 大标题走 B5 文字渐变（唯一允许渐变的地方）
   例外（有意为之，见各自注释）：hero 书法字为视觉装置；信纸与歌词为诗性
   排版；跑马灯为匀速循环（唯一合理曲线）。
