/**
 * Story Video Popup — Frontend Styles (v2.0)
 *
 * Melhorias v2:
 *  - GPU compositing: will-change + translateZ(0) nos elementos animados.
 *  - CSS containment (contain: layout style paint) no story container.
 *  - prefers-reduced-motion: respeito total às preferências de acessibilidade.
 *  - Safe area insets env() para iPhone notch e home indicator.
 *  - Tap targets mínimos 44px no mobile (WCAG 2.5.5).
 *  - Animação de entrada do botão flutuante (fade+scale em vez de display:block).
 *  - Animação de saída do overlay com classe .svp-closing (slide+fade).
 *  - Suporte a swipe-to-close no mobile (indicador visual).
 *  - Landscape mode no mobile: ajuste proporcional.
 *  - Backdrop blur nos botões de controle.
 *  - Barra de progresso com CSS transition (suaviza timeupdate do JS).
 *  - CTA responsivo em telas pequenas.
 *
 * NÃO hardcode cores ou tamanhos — use var(--svp-*).
 *
 * @package StoryVideoPopup
 * @version 2.0.0
