/* matches-accent.css — Matches 页 per-page accent 注入（节点 10 v2）
 *
 * 规则（per spec §2.4 + brief C6 + T1 minor M1 + T2 PR1 guardrail）:
 *   1) accent-6 (warm brown #6B5640) 共享 2 处 accent 表面（取代 v1 badge--ongoing 单一色块）:
 *      a) .match-card::before 左 2px border — hover 时 scaleY 0→1
 *      b) .match-card__placement 战绩 chip — italic + accent-6
 *   2) 不重复声明 --accent-current (per T1 minor M1) — 直接 var(--accent-6) 引用
 *      (per T2 PR1: accent-base.css 已定义 --accent-6 = #6B5640 单一来源)
 *   3) border-radius: 0 (C13) — 全部组件不例外
 *   4) transition 全用 var(--dur-micro) + var(--ease) — 无 cubic-bezier 字面量
 *   5) 无 @keyframes — 全 transition (C5/C11)
 *   6) accent 表面 ≤5% (左 border per hover + 战绩 chip italic)
 *
 * badge--ongoing v2 改为 outline-only（typography 化）— 由 hover translateY(-1px) 承担焦点感
