 * Тема «Зошит» (бренд «Рахуйка»): шкільний зошит у клітинку, синя кулькова ручка, червоні поля, жовтий маркер, рахівниця.
 * Калькулятор — як задача: «Дано» (комплектація) і «Відповідь» (ціна, підкреслена маркером).
 * Шрифти: Unbounded — заголовки й ціни, Onest — текст, Caveat — лише рукописне «Відповідь:».
 * Підключається після site.css замість theme.css (налаштування site.theme = zoshyt).
