/*
 * 一枝红杏 homepage「杏笺」(core/pages/homepage/yzhx2026) - homepage-only CSS: page wrap, low hero, quick links,
 * FAQ. The plans block and shared variables (--yz-x-*) are in plans.css (loaded first).
 * Design: yzhx-home-redesign/proposals/a-xingjian/style.css (prototype), plan task-e/PLAN_E.md §2.5.
 * Everything is scoped to .yz-home with own .yz-* classes, so the page renders the same under any Lagom style
 * (outside yzhx2026 the self-hosted Noto Serif SC is not loaded and headings fall back to the system serif).
