/* Trang chi tiết bài viết — Entra City
 * Lưu ý font: Mona Sans của theme chỉ có 1 weight (200 ExtraLight) nên in đậm bị "faux bold",
 * bài dài đọc mệt. Nội dung bài dùng Montserrat (đã load từ Google Fonts, đủ 100–900 + tiếng Việt).
 * Tiêu đề giữ font thương hiệu (1FTV Eleanor Goenka) nhưng weight 400 vì font chỉ có 1 weight.
 * html gốc = 14px nên dùng px cho cỡ chữ bài viết.
