/* ============================================================================
   图片转素描（sub-sketch）· 2026-09-23 · 开发员18号
   ----------------------------------------------------------------------------
   只作用于 #sub-sketch，不碰 style.css。
   设计主张：**纸与石墨** —— 暖白纸底 + 墨灰强调色，让界面本身就像一张画纸。
   与站内其它视觉区分：图片复刻=靛紫、模特换衣=粉、服饰穿戴=暖棕米白、**素描=石墨灰 + 纸白**。
   ⚠️ 注释里不写"星号紧跟斜杠"的连写（会让注释提前闭合）。
   ============================================================================ */

/* 图标配色：石墨灰（图片板块的卡片图标用类名 .f-ink）。
   ⚠️ 这条规则属于本功能自己的样式文件 —— 项目铁律：改别人的样式要新建独立 css，
      所以**不动 style.css**（那条规则和文件是由本文件承接的）。 */
