   СвойСофт — лендинг-эксперимент.
   Цифровой журнал + аналитическая панель: типографика задаёт
   характер, линии тонкие, поверхности плоские — без градиентов
   и теней. Одиночный акцент: бутылочно-зелёный.
   Шрифты: Unbounded (заголовки) / Inter (текст) / JetBrains Mono
   (цифры, индексы, лейблы).
