/* roster-accent.css — 队员名册页 per-page accent 注入
 *
 * 规则（per brief C6/C7/C8/C9/C11/C13 + springs.estate DNA 翻译）：
 *   1) red accent (--accent-wine 复用全局 token) 注入 3 处：
 *      a) .r-hero__title em — h1 中诗化字 navy (≤0.3%)
 *      b) .r-card:hover — 顶 2px navy 条 + 微抬升 (≤1.0%)
 *      c) .r-pager__btn:hover + .r-filter__select:focus — navy 边框入场 (≤0.5%)
 *   2) 不引入新 color token — 沿用 tokens.css 已有的 --accent-wine / --accent-1 / --accent-7 等
 *   3) border-radius: 0 (C13) — 全局规则
 *      例外：.r-card__avatar 与 .r-card__avatar--initial — 圆形身份徽章
 *      （同 .btn-circular C13 carve-out：仅用于"圆形身份"语义）
 *   4) transition 全用 var(--dur-micro) / var(--dur-reveal) + var(--ease)
 *   5) 无 @keyframes (C11)
 *   6) role badge 三态 (PLAYER / ALUMNI / ADMIN) — 学自 gallery-accent badge pattern
