/* Theme character for product screens (chat, diary panel, sign-in), the landing and the media center.
   Each theme differs in type, shape and texture, not only in colour:
   care  "Розовая"  — нежная и женственная: розовый с сиренью, округлый Nunito, мягкие тени без рамок, сердечко на активной вкладке;
   light "Светлая"  — нейтральная и универсальная: графит, белые карточки с тонкой рамкой, один тёплый акцент на данных;
   dark  "Тёмная"   — спортивная: графит и неоновый лайм, Oswald заглавными, рубленые углы, сегментные шкалы.
   Theme names describe appearance and never an account's gender. The rules live in docs/design/theme-character.md.
   Selectors are prefixed with the page class so they win over the older per-theme details without !important. */
