   Workspace Purchasing — MagnoliaX DS v2 "Monday" (light-first)
   MỌI selector đều nằm trong #workspace-purchasing. Cố ý KHÔNG dùng tên class
   trần (.btn/.card/.board/.pill/.tabs…) của magnolia-ds.css: những tên đó đã
   tồn tại trong styles.css của app và nạp toàn cục sẽ vẽ lại cả 14 workspace
   còn lại. Ở đây dùng tiền tố `pur-` + bọc trong id workspace ⇒ ảnh hưởng 0.
   Font Public Sans đã nạp sẵn ở index.html (400/700, có dấu tiếng Việt đủ).
