/*
 * Styles for demo_jp.html (DeepAR v5 eyewear try-on).
 *
 * Reworked to match the visual identity of the legacy page
 * (https://ar.virtry.net/demo_jp.html): a white, vertically-stacked, centered
 * layout — logo top-left, a landscape preview box, a horizontal thumbnail strip
 * with arrows, then a large App Store badge + QR, then a privacy note.
 *
 * The mechanics stay on the v5 stack: a `#deepar-preview` previewElement (the
 * SDK appends its own <canvas>), the dependency-free src/carousel.js contract,
 * and the loading / permission-denied screens driven by src/demo_jp.js.
