/*
 * Casiny Casino (AU) — static multi-page article build, adapted from the
 * templates/mostbet-tailwind-2 design system (tokens, header/drawer/button/
 * FAQ/table component shapes reused; the sportsbook one-pager itself is NOT
 * reused — this brand runs FOUR content pages: casino overview, mobile app,
 * welcome bonus, registration guide, each carrying its own hero + at-a-glance
 * table + prose sections + FAQ + on-page Responsible Gambling block).
 *
 * Class prefix `csn-` (Casiny). Palette deviates from the donor mockup —
 * deep purple/violet surfaces, gold primary CTA, magenta secondary accent —
 * so this stays visually distinct from mostbet-tailwind-2 side by side.
 *
 * Mobile-first. No build step, no libraries. Tables scroll/stack on narrow
 * viewports via .csn-table-wrap + data-label (css-layout §5). FAQ is native
 * <details>. Single <nav> per page, toggled for mobile via drawer (css-layout §4).
