/* =====================================================================
   ПРАВИЛО РОЗКЛАДКИ
   1. Секції (.section) завжди на всю ширину екрана: фон, лінії, смуги.
   2. Контент усередині — у .wrap: по центру, max-width --wrap, бічні
      поля --gutter ростуть разом з екраном (clamp).
   3. Блоки, що мають бути на весь екран, виходять з .wrap: hero-фото
      (bleed вправо), marquee, темна смуга «Підхід», контактна смуга.
   4. Порожні поля по боках — робочі: на ≥1500px туди виносяться
      номери секцій (.num стає липким у лівому полі).
   5. Базовий розмір шрифту трохи росте з екраном (html font-size),
      тож на 4K усе масштабується, а не губиться посередині.
