/* PbootCMS theme: gh-2026 — Luoyang Guohan industrial UI
   Adapted verbatim from the approved static prototype (assets/css/home.css).
   Layout reference: queclink.com.cn. Brand assets and content: lyguohan.com.
   No third-party runtime dependencies.
   Asset URLs: this file lives in /template/gh-2026/css/, so any future url()
   asset must be written as ../images/<file> (the prototype used assets/images/).
   The prototype stylesheet contained no url() references, so none were rewritten.
   Sections 1-10 below are the untouched prototype design system; the final
   "PbootCMS integration" section only adds styles for CMS-generated markup. */
