   SQL-тренажёр · оформление

   Типографика кодирует режим работы, а не украшает:
     IBM Plex Serif — теория и разборы (это читают),
     IBM Plex Sans  — интерфейс и условия заданий (это сканируют),
     IBM Plex Mono  — SQL, результаты, планы (это набирают).
   Палитра построена вокруг синего PostgreSQL; зелёный, янтарный
   и красный несут статус, а не акцент.
   ===================================================================== */

/* Светлая палитра — база. Тёмная включается системной настройкой
   или явным выбором пользователя (атрибут data-theme). */
