/* Surf — экран «Эфир» (ARCHITECTURE §7 «Оверлей»). Только на токенах surf-app.css. Экран — .screen (absolute inset 0 внутри
   fixed #app на 100lvh: под safe-area тоже видео, никакой полосы), сцена чёрная, видео object-fit: cover (.fit-contain — константа
   STREAM_FIT в surf-player-ui.js). Жесты ловит вся сцена (touch-action: none, без выделения); слои поверх видео (.st-scrim, .st-shade,
   .st-lower, титр, тосты) касаний не перехватывают — pointer-events: none; кнопки — только сами кнопки при показанном управлении.
   В покое поверх ничего. Титр = @handle + лайки/комментарии момента (.st-lstats, общий примитив .stats) + описание.
   Композиция оверлея по зоне большого пальца: колонка кнопок справа и титр слева стоят на одной
   нижней линии bottom = sab + 24; сверху только шеврон «домой» и звук. Под титром не стекло, а мягкий градиент снизу сцены.
   Грузится как /src/css/surf-stream.css?v=$version. */
