/**
 * 全站统一顶栏 / 页内工具条
 * - Tier 1: .sa-site-bar — 52px sticky，品牌 + 页标题 + 元信息/操作
 * - Tier 2: .sa-page-toolbar — 页内筛选（可选第二行）
 * 兼容类名：.index-header / .global-search-container / .plate-toolbar（品牌行已迁出时）
 *
 * 契约（Page Shell）：
 * - 宽度 / 左右 gutter 只通过 --sa-topbar-max-width / --sa-topbar-px（移动端 --sa-topbar-px-mobile）
 * - 正文用 .sa-page-shell 或 .container，与顶栏 .sa-site-bar__inner 左右对齐
 * - 禁止页级 CSS 覆盖 .sa-site-bar__inner / .index-header-inner 的 max-width / padding / gap
 * - 密度页若需加宽：仅在 body 上覆盖 --sa-topbar-max-width，勿单独改 --sa-topbar-px
 *
 * 依赖 finance_nav/tokens.css — 请在模板中先 include _static_site_css.html（勿 @import，子表不带 ?v=）
