/* ============================================================
   BIRGA — «Ночной выпуск» (арт-дирекция v3, 2026-08-08).
   Дневник, снятый как фильм, с деталями торгового терминала.

   Опоры: тёплый чёрный (не синий SaaS), зерно плёнки, один
   акцент — янтарь. Editorial-типографика: Unbounded (дисплей),
   Golos Text (текст), JetBrains Mono (цифры/метки/тикер).

   DO NOT: индиго/фиолетовые градиенты, стеклянные карточки,
   неон, Inter, стоковые улыбки, 3D-шарики.
