/* ---- v5.3.2 打印加强（设置开关 pdfPrintEnhance，v5.3.3 颜色自定义）----
   浅灰框线加深（纸质打印更清晰）；主题色系（luxury/wireframe/geometric/panel）线色本就较深，不适用。
   v5.3.3：不再依赖页面 id（预览/舞台/引擎 HTML 均有 .quote-document 与 .pdf-print-strong 类），
   用双份类名把特异性提升至 0-4-0 以上（+4 个 :not()），高于全部样式段(0-3-0)与编辑器生成 CSS(0-2-0)；
   颜色取 --pdf-enhance（用户可自定义，默认 #93a3b5），行线取 --pdf-enhance-line；
   【移植改动】行线原为 color-mix(in srgb, var(--pdf-enhance) 50%, #ffffff)——浏览器渲染没问题，
   但 html2canvas 解析不了 color-mix（报 unsupported color function "color"）。本插件没有服务端
   打印引擎、导出走 html2canvas 截图管线，故改为 JS 预先算好写入 --pdf-enhance-line
   （见 app.js 的 patchEnhanceLineColor），输出颜色与原来一致 */
