/* ============================================================
   Reeve — 质感精修层（加载于 im.css 之后）
   原则：
   · 墨色为主，人物色降为低饱和 duotone（衬线首字母 + 同色细环）
   · accent 只留给「决定」与 Reeve 的存在；其余信号一律收敛
   · 计时 / 标签统一 JetBrains Mono 微字号；数字 tabular
   · 卡片光影更扁：1px 细线 + 一层很远的环境影
   · Agent 的存在感 = 呼吸的 orb + 思考波纹 + mono 签名，而非更多颜色
