/* liqi.page — магазин электронных книг Linden & Quill.
   Система снята с penguin.co.uk (13.11.2026): белая шапка 96 с поиском-таблеткой и чёрной кнопкой,
   сплошная насыщенная заливка под плитками, плитки r24 с зазором 16 и подписью снизу слева,
   контейнер 1280 при полях 80. Цвет свой: липовая зелень издательства, доведённая до насыщенной,
   акцент лайм — только главные кнопки и точка статуса. Обложки — предметы (3D-книга, стена обложек). */
