/* ============================================
   信息页样式 - info-pages.css
   ============================================
   作用：
   1. 统一 `contact / terms / privacy` 三类信息页的视觉骨架和材质风格。
   2. 让说明页依然停留在盐憩的海层世界里，而不是退回普通白底文档页。
   3. 为首屏、段落导航、联系卡、表单和页脚提供同一套安静的玻璃空间。
   阅读顺序：
   1. 页面整体背景
   2. 首屏
   3. 导航与正文壳体
   4. 联系页特有模块与响应式
*/

   这三页不是普通白底信息页，而是盐憩里一层更浅、更静的说明水域。
   背景、留白和材质都要比正文页更平稳，但仍然保持海层感和玻璃雾感。 */
