/* ============================================================================
 * 暮色手帖 · 档案室版（archive.css）
 * ----------------------------------------------------------------------------
 * 以「莱茵生命 R-01 档案室」视觉体系重制全站：暖白底板 / 墨黑 / 莱茵橙，
 * DIN 窄体技术字 + 等宽批注，部门制导航与档案编号。
 * 与原站共用 app.js / entries.js，DOM 挂钩（#calendarGrid、#recentList、
 * #categoryGrid、#articleBody 等）完全一致，只换皮不换逻辑。
 *
 * 主题：默认 = 档案室（暖白）；body.light = 夜间值班（暗色机房）。
