/**
 * TORRAS TVC Case Study — 页面专属布局（.wd-tt-* 前缀）。
 * 来源：dotnfilm-optisolex 3/project/TORRAS TVC Case Study.dc.html 内联 style 抽取。
 * 颜色一律引用共享层 --wd-* token（原型色值全部命中共享表，无需新增局部色彩）。
 * 构图性渐变遮罩用 rgba(10,10,10,x)（= --wd-bg #0A0A0A 底色，CSS 渐变无法直接对 var 加 alpha，
 * 故此处保留字面 rgba 并注明对应 token）。
 * 桌面优先，多列 grid 在 ≤768px 单列降级。
 * 与 work-designs/torras-lab/（wd-tl）是不同案例，前缀 wd-tt 不混淆。
