/*
 * مركز الألعاب — شريط علوي ثابت لزر «تسجيل / دخول» (و«الأصدقاء» بعد الدخول).
 *
 * Root cause (React bundle, not edited): the hub screen is
 *   div.fixed.inset-0.flex.flex-col.justify-center.overflow-y-auto
 * with the account button as `absolute top-4 right-4` inside it.
 *  1. justify-content:center on a scroll container whose content is taller
 *     than the viewport overflows the content UPWARDS: the «مركز الألعاب»
 *     title ends up above the scroll origin (unreachable) and the cards move
 *     up under the button, which stays at the scroll origin → the button
 *     appears in the middle of the cards (worst on iPhone Safari).
 *  2. position:absolute inside the scroll container makes it scroll away.
 *  3. viewport-fit=cover without safe-area insets puts it under the notch.
 *
 * Scope: only the hub screen (the one containing the games grid
 * .grid.max-w-3xl next to the account button). Other screens are untouched.
 * Without :has() support (iOS < 15.4) the page simply keeps its old layout.
