/* AstraTrade Quantum Research Console — 二级页面 design system
 *
 * 继承首页 (tokens.css) 的色板 + Inter + radius, 增加 7 个 design 元素:
 *   1. workspace layout (sidebar + main + inspector)
 *   2. state machine pill (PENDING → ACTIVE → DONE)
 *   3. sparkline rows (inline svg trend in table)
 *   4. heatmap matrix (strategy × ladder)
 *   5. sankey funnel (signal → gate → fill → outcome)
 *   6. audit timeline (append-only event stream)
 *   7. allowed-actions panel (radio + confirm)
 *
 * 红线: 新增模板不再用 inline <style>; legacy base_shell inline 不算违规.
