/*
  Layout: sidebar + header + main grid. Брейкпоинты (пересмотрены — desktop
  и mobile теперь ДЕЙСТВИТЕЛЬНО разные layout, не один мобильный на все
  размеры):
    Desktop   >= 1440px  — полный sidebar, KPI в 1 строку (5, на >=1920 — 7)
    Laptop    1280–1439px — полный sidebar, чуть теснее карточки
    Tablet-L  1024–1279px — sidebar авто-компактный (иконки), KPI 3+3, grid 2 колонки
    Tablet    768–1023px  — sidebar скрыт, 1 колонка
    Mobile    < 768px     — bottom navigation, sidebar скрыт

  ВАЖНО: bottom navigation показывается ТОЛЬКО < 768px — это единственное
  место, где .mobile-bottom-nav получает display отличный от none.
