/**
 * 金融知识学习中心 · 站点版三栏形态（板块页 + 模块详情页共用）
 * 形态照搬旧版 SPA（设计工作区/金融知识学习中心/金融知识学习中心.html），风格改造为站点体系：
 *   - 配色/边框/字体全部取 Tabler token（--tblr-*），跟随站点暗/浅主题，不硬编码暗色
 *   - 类名加 fl- 前缀；JS 生成的实验室面板沿用旧版类名（lab-panel 等），统一限定作用域
 *   - 无金融系统栏/进度/保存状态/冲突对话框/我的记录（按菲戈指示去掉）
 * 注入：inc/assets.php 仅在 /knowledge/finance/ 路由入队；模板 knowledge/part-finance-center.php
