/**
 * QuickPeek vertical view ("reels" overlay).
 *
 * Loaded only by resources/views/quickpeek.blade.php. Everything here is scoped
 * under #qp-vv (the overlay), body.qp-vv-open (page state while open), or the
 * .qp-vv-* affordance classes injected by public/js/quickpeek-vertical.js.
 *
 * The overlay does NOT own the post-card markup — it re-themes the classic
 * .instagram-post-card DOM, which is styled by ~1700 lines of inline CSS in
 * quickpeek.blade.php and the card component. That CSS renders later in the
 * document than this file (body <style> vs head <link>), so ties go to the page.
 * The !important density below is deliberate: this file is a retheme layer and
 * must win those fights.
