 `computeBlocks(student)` returns only blocks where the student has all 3 subject scores, sorted by total desc. Used by the student detail card.
 
-The SQL preset "Top 10 điểm khối cao nhất – Long An" materialises all 49 blocks as a `UNION ALL` CTE, picks each student's best via `ROW_NUMBER() OVER (PARTITION BY so_bao_danh ORDER BY s DESC, k)`, then ranks across students.
