/* ============================================
   THẦN SỐ HỌC — trang /than-so-hoc/ (thiết kế lại 01/10/2026)
   Hệ thiết kế: con số là nhân vật chính.
   - Font: Nunito cho cả trang (--ff-d tiêu đề + số đậm 800–900, --ff-b/--ff-u chữ đọc, nhãn) — biến lấy từ cute.css (06/10/2026).
   - Hình: vòng 9 số + sao 9 cánh {9/4} + Tetractys của Pythagoras; vòng sóng lan toả; kim tự tháp 4 đỉnh cao.
   - Bố cục: mỗi phần là một "chương" đánh số 01–10; máy tính ≥1200px có mục lục dính bên trái.
   - Chiều rộng đồng bộ trang chủ: tối đa --site-w (1500px), lề 16px (≤768) / 32px (>768).
   - Màu: biến --tsh-* — cute.css ghi đè cho giao diện "Kẹo bông" (sáng mặc định, tối = đêm tím).
