/* ============================================================
 * Sticky Bottom CTA — Phase 10 Sprint 1 (2026-05-09)
 *
 * Barre fixe bas mobile sur landing/pricing/marketplace/blog.
 * Apparaît après scroll au-delà du hero, se cache près du footer.
 * Driver : `app/javascript/controllers/sticky_cta_controller.js`.
 *
 * Pattern : utilisé par Stripe, Linear, Notion landing pages.
 * Toujours masqué sur >= lg (sidebar/topbar prennent le relais).
 *
 * État : `.is-visible` ajouté/retiré par le controller. Sans la
 * classe, le bar est translaté hors écran (transform translateY 100%).
 * ============================================================ */
