 *
 * 设计意图（保留蓝色基调、整体观感明显焕新）：
 *   1) 主轴蓝从"极穹靛蓝（紫色调蓝 H≈226°）"切到"皇家钴蓝（H≈221°）"，
 *      色相向青色方向回拉约 5°、彩度提升约 10%，整体气质从"极地仰望"切到"海湾远眺"；
 *   2) 暖对位锚点从"薄暮紫罗（紫罗 H≈270°）"切到"余晖琥珀（金黄 H≈38°）"，
 *      色相旋转约 130°，是本代最明显的视觉差异点——从"湾港极夜冷调对比"切到"湾内日落金辉对比"；
 *   3) 冷对位锚点从"极光晶青（蓝绿 H≈189°）"切到"翡翠琉璃（绿色 H≈160°）"，
 *      色相再回拉 29°、偏向"湾内潜珊瑚礁绿"的湿润高光感；
 *   4) 画布从"曙穹微蓝（偏紫 indigo-50）"切到"晨曦薄蓝（偏青 blue-50）"，
 *      与主轴同色系，画布更"通透海雾"；
 *   5) 所有阴影从"极穹族（rgba 30,27,75）"迁至"湾蓝族（rgba 23,37,84 / 12,74,110）"，
 *      让投影更贴近"湾水蓝墨"的湿润低噪声氛围；
 *   6) hero 渐变核心节奏由"极夜深穹 + 极光青晕 + 紫罗"重写为"海渊蓝穹 + 翡翠晕 + 琥珀"三段式；
 *   7) Logo / Favicon 由"极星穹塔 + 三道极光环 + 北极星徽"重塑为
 *      "蔚蓝罗盘 + 三道航波环 + 琥珀指针徽"。
 *
 * 工程命名（v13 重命名）：
 *   • CSS class / 变量前缀：qmr- / --qmr-（v12 为 qas- / --qas-）
 *   • Data 属性前缀：       data-qmr-*（v12 为 data-qas-*）
 *   • PHP 函数前缀：        qmar_*（v12 为 qastra_*）
 *   • 文本域：              qq-marina（v12 为 qq-astra）
 *   • 主 JS：               marina.js（v12 为 astra.js）
