/* ============================================================
 * 鸽子笼看板 ·「晨雾纸面 / 夜航甲板」共享样式（redesign-spec §2–§8）
 *
 * 亮主题 = 晨雾纸面（暖纸 + 靛蓝）；暗主题 = 夜航甲板（深墨蓝 + 月白 + 柔靛）。
 * 全部颜色走 CSS 变量；Tailwind 语义类由 tailwind.config.newui.js
 * 映射到同一组变量（RGB 三元组）。`white` 已重映射为 --t-contrast，
 * 存量 border-white/10、bg-white/5 自动随主题翻转为发丝线/墨水洗。
 * 毛玻璃只用于悬浮层（侧栏/顶栏/移动底栏/弹窗/建议浮层/Toast）；
 * 内容卡片 = 近白实底 + 发丝线 + 耳语阴影。动效只动 transform/opacity。
