/* ===== D2 技术债 · 内联样式收敛用的类（2026-10-14）=====
 * 用途：把 pro-mod2.js / pro-mod4.js 里**重复出现**的内联 style 换成类，值逐字照抄，不加 !important。
 * 为什么落在这个文件：本文件在 index.html 里**没有 ?v=**（改它不需要动 index.html）；
 *   pro-mod1..3.css 同样可用，其余 pro-css 都带 ?v=（改内容而不抬版本会被 check-versioning 判 FAIL）。
 * 等价性证据（真机 Chrome 154 · pro-mod4.css 的真实级联位置）：每个类 vs 它要替代的内联样式，
 *   在 #page-knowledge/#page-growth/#page-studyroom/body 四个宿主 × div/span/.v17-btn/input 四种形态下，
 *   **全部计算样式逐条 0 差异**；落地前页面里命中这些类的元素 = 0 ⇒ 对现存渲染零影响。
 * 对应关系（内联值 → 类）：仅这 9 组，其余单例内联样式一律不动。 */
