/*
 * Vertical "shorts" viewer — /videos/watch and /moments/watch (markup: Pages/Shared/_ShortsViewer.cshtml,
 * behaviour: wwwroot/js/vuexr.shorts.js). Hand-written: the precompiled Tailwind build can't produce
 * these arbitrary sizes. Colors come from the theme (.dark on <html>, --primary, .box cards).
 *
 * Layout (desktop, >=1200px):  [info]  [ 9:16 player ]  [actions]        [up/down arrows, far right]
 * Comments open:               player + actions slide left, the info block moves inside the player,
 *                              the comments panel takes ~480px on the right.
 * Tablet (768-1199px):         comments overlay from the right instead of pushing the player.
 * Phone (<768px):              full-screen player, actions overlaid, comments as a bottom sheet.
