 * Khóa học Điều phối BIM — BIM Coordinator
 * Toàn bộ selector nằm dưới .vdt-bimc-page nên không ảnh hưởng trang khác.
 *
 * PHÂN BIỆT VISUAL VỚI PAGE 2 (.vdt-bimm-page / BIM Manager):
 *  - Page 2 = information management: lưới blueprint đều, thẻ dữ liệu, bảng.
 *  - Page 3 = coordination: các LỚP chồng nhau, ĐƯỜNG NỐI giữa các bước,
 *    marker xung đột màu gold, pipeline zig-zag. Accent gold dùng cho
 *    "điểm xung đột"; cyan/blue vẫn là màu nền hệ thống.
 *
 * LƯU Ý ĐỘ ƯU TIÊN (đã gây lỗi ở các landing page trước):
 *  - `body.vdt-page h1..h6` là (0,1,2) nên mọi rule màu chữ tiêu đề ở đây
 *    đều phải có tiền tố .vdt-bimc-page để thắng.
 *  - `.vdt-bimc-main p` là (0,2,1), sẽ đè mọi `.vdt-bimc-page .vdt-bimc-<tên>`
 *    (0,2,0). Vì vậy rule <p> chung chỉ áp cho <p> KHÔNG có class.
 *  - CẢNH BÁO: `p:not([class])` KHÔNG phải (0,2,1). `:not()` cộng specificity
 *    của thứ bên trong, `[class]` là attribute selector nên tổng là (0,3,1).
 *    Nó đè cả `.vdt-bimc-page .vdt-bimc-outcome p` (0,2,1) -> từng gây chữ tối
 *    trên nền navy. Xem khối "NỀN TỐI" ngay dưới phần Base.
