/* =====================================================
 * STICKY CTA — Fixed "Free DXO Text" button
 * -----------------------------------------------------
 *  - Desktop (>= 769px): vertical tab pinned to right edge,
 *    text vertical + arrow BELOW
 *  - Mobile  (<= 768px): full-width bar pinned to bottom
 *
 * Color: deep Jyoro teal (#1F807B) — based on DXO 4-core
 *   "Jyoro" color (#2EA9A2) but darkened for WCAG AA contrast
 *   with white text. Balances the red CTAs site-wide so the
 *   sticky CTA doesn't compound the "red-heavy" impression.
 *
 * To DISABLE: remove the 2 references from each HTML file:
 *   <link rel="stylesheet" href="assets/css/sticky-cta.css">
 *   <aside class="sticky-cta">...</aside>
