/* ═══════════════════════════════════════════════════════════════
   tests-tests.ru — design.css (v1562)
   Слой современного оформления поверх style.css.

   Принципы:
   — полная ширина на широких экранах (до 2200px), плавная сетка;
   — объём: многослойные тени, градиенты, «клавиши» с эффектом нажатия;
   — цвет раздела (--accent / --accent-soft / --top-section-accent) и тема
     шапки из админки (--hero-grad / --nav-bg) НЕ переопределяются —
     слой только использует эти переменные;
   — три режима: телефон (≤680), планшет (681–1024), компьютер (≥1025).
   Файл подключается сразу после style.css в includes/header.php.
