/*
 * BrowXenna — Premium Academy / "Ваш подарок"
 * Cinematic luxury education dashboard. Изолирован под .lkx-academy* + .lkx-player*.
 * Расширяет токены из lk-premium.css (warm milk, bronze, graphite).
 *
 * NB: sidebar (.lkx-side*, .lkx-aside-grid, .lkx-shell--aside) переехал в lk-premium.css,
 * чтобы все 4 страницы LK использовали единый dashboard-layout.
