/* 咖爷咖啡学院页样式。
   来源：设计稿 caye-website(2026-08-20) academy.html 的 <style> 块，
   按注释分节抽取 Hero / Shared section helpers / Contact-QR /
   Coffee Academy page / Learning Path / Instructor carousel /
   Empowerment，外加 Responsive 中与学院相关的规则。
   本文件手工维护，不由 build_*_final_pages.py 生成 —— 生成器不碰它。
   只在 /academy.html 与 /en/academy.html 加载，未加前缀的 .section /
   .container 等只影响这两页。 */
