/* events.css — phần đặc thù của module "events" (Lịch – Sự kiện): danh sách sự kiện, lưới tháng, khối "Sự kiện sắp tới", trang chi tiết.
   Quy ước (docs/theme/contract.md mục 8): chỉ bổ sung phần đặc thù của module, dùng token --mt-* (có giá trị dự phòng để không vỡ khi theme
   chưa nạp token), lớp BEM mt-event*, mt-events*. Các lớp nền mt-* (card, list, datechip, badge, chip, filter, btn, empty, dl...) do hệ thiết kế
   của theme định nghĩa.

   PHẦN A — dự phòng: dùng :where() (độ ưu tiên 0) để khi theme hiện hành KHÔNG có hệ thiết kế mt-* (vd. theme mặc định của lõi trên sandbox) trang
   vẫn dễ đọc; khi theme mn-muongthanh đã định nghĩa lớp nào thì định nghĩa của theme luôn thắng.
   PHẦN B — bố cục riêng của module. */
